b1afda0e33 mips: nand: make use of mtd_to_nand() where appropriate 
mtd_to_nand() was recently introduced to avoid direct accesses to the
mtd->priv field. Update all MIPS specific implementations to use this
helper.

832f5dacfa MIPS: Remove all the uses of custom gpio.h 
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.

c02a505e5a MIPS: Alchemy: DB1xxx: Explicitly set 50MHz clock for I2C/SPI units. 
Add an explicit call to set the desired rate to get the correct
clock routing for the PSC clocks.  It wasn't broken before, but
now it's less affected by bootloader changes.

9cf12167e9 MIPS: Alchemy: add helpers to access static memory ctrl registers. 
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.

1c043f16a0 MIPS: Alchemy: Add RTC device to all devboards 
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.
