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.

Rewritten XXS1500 PCMCIA socket driver, standalone (doesn't depend on
au1000_generic.c) and added carddetect IRQ support.

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.

Replace a few GPIO register accesses in the board init code with calls to
the gpio api.

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.

Since memsize is unsigned, it would seem better to use strict_strtoul that
strict_strtol.
A simplified version of the semantic patch that makes this change is as
follows: (http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@s2@
long e;
position p;

strict_strtol@p(...,&e)
