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.

2530738013 MIPS: ath25: Remove unused DMA helper functions.
These got merged with the ath25 support after 4e7f72660c (MIPS: Remove
unnecessary platform dma helper functions) had already removed them for
all other platforms.

d631fc6070 MIPS: Create a common <asm/mach-generic/war.h>
11 platforms require at least one of these workarounds to be enabled; 22
platforms do not.  In the latter case we can fall back to a generic version.

Note that this also deletes an orphaned reference to RM9000_CDEX_SMP_WAR.

a747371748 MIPS: ath25: add board configuration detection
All boards based on AR5312/AR2315 SoC have a special structure located
at the end of flash. This structure contains board-specific data such as
Ethernet and Wireless MAC addresses. The flash is mapped to the memmory
at predefined location.
