pinctrl: pinconf-generic: Allow driver to specify DT params
Additionally to the generic DT parameters, allow drivers to provide
driver-specific DT parameters to be used with the generic parser
infrastructure.
To achieve this 'struct pinctrl_desc' is extended to pass custom pinconf
option to the core. In order to pass this kind of information, the
related data structures - 'struct pinconf_generic_dt_params',
'pin_config_item' - are moved from pinconf internals to the
pinconf-generic header.
Additionally pinconfg-generic is refactored to not only iterate over the
generic pinconf parameters but also take the parameters into account
that are provided through the driver's 'struct pinctrl_desc'.
In particular 'pinconf_generic_parse_dt_config()' and
'pinconf_generic_dump' helpers are split into two parts each. In order
to have a more generic helper that can be used to process the generic
parameters as well as the driver-specific ones.
v2:
- fix typo
- add missing documentation for @conf_items member in struct
- rebase to pinctrl/devel: conflict in abx500
- rename _pinconf_generic_dump() to pinconf_generic_dump_one()
- removed '_' from _parse_dt_cfg()
- removed BUG_ONs, error condition is handled in if statements
- removed pinconf_generic_dump_group() & pinconf_generic_dump_pin
helpers
- fixed up corresponding call sites
- renamed pinconf_generic_dump() to pinconf_generic_dump_pins()
- added kernel-doc to pinconf_generic_dump_pins()
- add kernel-doc
- more verbose commit message
