irqdomain.c's kernel-doc exists, but is not plugged into Documentation/
yet.
Before plugging it in, fix it first: irq_domain_get_irq_data() and
irq_domain_set_info() were documented twice. Identically, by both
definitions for CONFIG_IRQ_DOMAIN_HIERARCHY and !CONFIG_IRQ_DOMAIN_HIERARCHY.
Therefore, switch the second kernel-doc into an ordinary comment -- change
"/**" to simple "/*". This avoids sphinx's: WARNING: Duplicate C
declaration
Next, in commit b7b377332b96 ("irqdomain: Fix the kernel-doc and plug it
into Documentation"), irqdomain.h's (header) kernel-doc was added into
core-api/genericirq.rst. But given the amount of irqdomain functions and
structures, move all these to core-api/irq/irq-domain.rst now.
Finally, add these newly fixed irqdomain.c's (source) docs there as
well.

The irqdomain documentaion became obsolete over time. Update and extend
it a bit with respect to the current code and HW.
Most notably the doubled documentation of irq_domain (from .rst and .h)
was unified and let only in .rst. A reference link was added to .h.
Furthermore:
* Add some 'struct' keywords, so that the respective structs are
hyperlinked
* :c:member: use where appropriate to mark a member of a struct
* Rephrase some wording to improve readability/understanding

The improvements include:
* Capitals in headlines.
* Add commas: for easier reading, it is always desired to add commas
at some places in text. Like before adverbs or after fronted
sentences.
* 3rd person -> add 's' to verbs.
* End some sentences with period and start a new one. Avoid thus heavy
sentences.

Just note in the docs:
1) A PCI device as an example for shared interrupts
2) A sparse tree can be used for interrupts too
3) i8259s which have 8 pins

Many of irqdomain.h's functions are referenced in Documentation/ but are
not properly documented. Therefore, document these.
And use "Returns:" tag consistently, so that it is properly generated in
the resulting docs.

This makes the code more compact.
Note that irq_domain_create_hierarchy()'s handling of size is now part of
info's initializer (using the ternary operator). That makes more sense

Most irq_domain_add_*() functions are unused now, so drop them. The
remaining ones are moved to the deprecated section and will be removed
during the merge window after the patches in various trees have been
merged.
Note: The Chinese docs are touched but unfinished. I cannot parse those.

All irq_domain_add_*() functions are going away. PowerPC is the only
user of irq_domain_add_nomap() and there is no irq_domain_create_nomap()
complement.
Therefore, to align with the rest of the kernel, rename
irq_domain_add_nomap() to irq_domain_create_nomap() and accept a
fwnode_handle instead of a device_node.

irq_domain_add_linear() is going away as being obsolete now. Switch to
the preferred irq_domain_create_linear(). That differs in the first
parameter: It takes more generic struct fwnode_handle instead of struct
device_node. Therefore, of_fwnode_handle() is added around the
parameter.
Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

irq_domain_add_simple() is going away as being obsolete now. Switch to
the preferred irq_domain_create_simple(). That differs in the first
parameter: It takes more generic struct fwnode_handle instead of struct
device_node. Therefore, of_fwnode_handle() is added around the
parameter.
Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

irq_domain_add_*() interfaces are going away as being obsolete now.
Switch to the preferred irq_domain_create_*() ones. Those differ in the
node parameter: They take more generic struct fwnode_handle instead of
struct device_node. Therefore, of_fwnode_handle() is added around the
original parameter.
Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

There is no reason to export the function as an extra symbol. It is
simple enough and is just a wrapper to already exported functions.
Therefore, switch the exported function to an inline.

All uses of of_node_to_fwnode() in non-irqdomain code were changed to
"officially" defined of_fwnode_handle(). Therefore, the former can be
dropped along with the last uses in the irqdomain code.
Due to merge logistics the inline cannot be dropped immediately. Move it to
a deprecated section, which will be removed during the merge window.

of_node_to_fwnode() is irqdomain's reimplementation of the "officially"
defined of_fwnode_handle(). The former is in the process of being
removed, so use the latter instead.

Add new function *_twothreecell() to extend support to parse three-cell
interrupts which encoded as <instance hwirq irqflag>, the translate
function will retrieve irq number and flag from last two cells.
This API will be used in gpio irq driver which need to work with
two or three cells cases.

The "real" linux/types.h UAPI header gracefully degrades to a NOOP when
included from assembly code.
Mirror this behaviour in the tools/ variant.
Test for __ASSEMBLER__ over __ASSEMBLY__ as the former is provided by the
toolchain automatically.
