Clean out stray unused board_reset() calls in pb1x boards, the PB1000 is
different from the rest and gets private methods.
(Cleanup after 32fd6901a6d8d19f94e4de6be4e4b552ab078620)

Create own directory for DB1200 code and update it with new features.
- SPI support:
- tmp121 temperature sensor
- SPI flash on DB1200
- I2C support
- NE1619 sensor
- AT24 eeprom
- I2C/SPI can be selected at boot time via switch S6.8
- Carddetect IRQs for SD cards.
- gen_nand based NAND support.
- hexleds count sleep/wake transitions.

Eliminate the sharing of IRQ names among the differenct Alchemy
variants. IRQ numbers need no longer be hidden behind a
CONFIG_SOC_AU1XXX symbol: step 1 in my quest to make the Alchemy
code less reliant on a hardcoded subtype.
This patch also renames the GPIO irq number constants. It's really
an interrupt line, NOT a GPIO number!
Code which relied on certain irq numbers to have the same name
across all supported cpu subtypes is changed to determine current
cpu subtype at runtime; in some places this isn't possible so
a "compat" symbol is used.
Run-tested on DB1200.

remove board_init_irq(): On all in-kernel boards it is sufficient to
initialize board interrupts in an arch_initcall by using the default
linux irq functions.
Some small irqmap.c files have been folded into board_setup files.
Run-tested on DB1200; compile-tested on all other affected boards.

All Alchemy development boards have external CPLDs with a few registers
in them. They all share an identical register layout with only a few
minor differences (except the PB1000) in bit functions and base
addresses.
This patch
- adds a primitive facility to initialize and use these external
registers,
- replaces all occurrences of bcsr->xxx accesses with calls to the new
functions (the pb1200 cascade irq handling code is special).
- collects BCSR register information scattered throughout the board
headers in a central place.

This patch attempts to modernize core Alchemy interrupt handling code.
- add irq_chips for irq controllers instead of irq type,
- add a set_type() hook to change irq trigger type during runtime,
- add a set_wake() hook to control GPIO0..7 based wakeup,
- use linux' IRQF_TRIGGER_ constants instead of homebrew ones,
- enable GENERIC_HARDIRQS_NO__DO_IRQ.
- simplify plat_irq_dispatch
- merge au1xxx_irqmap into irq.c file, the only place where its
contents are referenced.
- board_init_irq() is now mandatory for every board; use it to register
the remaining (gpio-based) interrupt sources; update all boards
accordingly.
Run-tested on Db1200 and other Au1200 based platforms.

Not every alchemy-based board might want these options forced on it,
and most of this stuff seems to be intended for devboard code anyway.
Remove commandline mangling code out of common chip code and instead
add relevant sections to all in-tree boards to not change existing
behaviour.

Share some code and merge small files:
- Extract the prom init code from all devboard files (they only differ in
memory configuration).
- Merge the irq configuration into board setup code.
- Merge smaller files into board setup code.

This should ease sharing of common devboard code.
