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.

*(1) GPIOLIB=y, ALCHEMY_GPIO_INDIRECT=y:

*(2) GPIOLIB=y, ALCHEMY_GPIO_INDIRECT=n:
|

* A gpiochip for the 75 GPIOs is registered.
|
||||
*
|
||||
*(3) GPIOLIB=n, ALCHEMY_GPIO_INDIRECT=y:
|
||||
* the boards' gpio.h must provide the linux gpio wrapper functions,
|
||||
*
|
||||
*(4) GPIOLIB=n, ALCHEMY_GPIO_INDIRECT=n:
|
||||
* inlinable gpio functions are provided which enable access to the
|
||||
* Au1300 gpios only by using the numbers straight out of the data-
|
||||
* sheets.
|
||||
|
||||
* Cases 1 and 3 are intended for boards which want to provide their own
|
||||
* GPIO namespace and -operations (i.e. for example you have 8 GPIOs
|
||||
* which are in part provided by spare Au1300 GPIO pins and in part by
|
||||
* an external FPGA but you still want them to be accssible in linux
|
||||
* as gpio0-7. The board can of course use the alchemy_gpioX_* functions
|
||||
* as required).
