This introduces threaded carddetect irqs for the db1200/db1300 boards.
Main benefit is that the broken insertion/ejection interrupt pairs
can now be better supported and debounced in software.

We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.

The MIPS Alchemy db1300 dev board depends on interrupt.h. Explicitly
include it instead of relying on the public mmc header host.h.

mtd_to_nand() was recently introduced to avoid direct accesses to the

Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS
machines, and each machine type provides its own gpio.h. However
only a handful really implement the GPIO API, most just forward
everythings to gpiolib.

The Alchemy machine is notable as it provides a system to allow
implementing the GPIO API at the board level. But it is not used by
any board currently supported, so it can also be removed.

For most machine types we can just remove the custom gpio.h, as well
as the custom wrappers if some exists. Some of the code found in
the wrappers must be moved to the respective GPIO driver.

A few more fixes are need in some drivers as they rely on linux/gpio.h
to provides some machine specific definitions, or used asm/gpio.h
instead of linux/gpio.h for the gpio API.

This patch changes the static memory controller registers to offsets
from base, prefixes them with AU1000_ to avoid silent failures due to
changed addresses and introduces helpers to access them.

No functional changes, comparing assembly of a few select functions shows
no differences.

All Devboards can use the 32kHz counter as a RTC device.

Also delete the custom CMOS RTC header, which can be used for the
DS1693 on the PB1500.  But since it doesn't have a buffer battery
it is as useful as the on-chip RTC which I prefer.
