8f3c4537bb ARM: gpio: make trivial GPIOLIB implementation the default
Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead.  This means that by default, you get the trivial implementation
and only have to do something extra if you need to.  This should
encourage the use of the trivial default implementation.

As an additional bonus, several gpio.h header files become empty.

01e7dc89d0 ARM: gpio: consolidate gpio_to_irq
Many of the gpio_to_irq implementations use the gpiolib version of this
function.  Provide the standard gpiolib gpio_to_irq() for everyone, but
allow platforms to override it if they wish.  Add the neccessary
overrides for those platforms which do not use the standard definition.

22fe678376 ARM: gpio: consolidate trivial gpiolib implementations
Consolidate 24 trivial gpiolib implementions out of mach/gpio.h
into asm/gpio.h.  This is basically the include of asm-generic/gpio.h
and the definition of gpio_get_value, gpio_set_value, and gpio_cansleep
as described in Documentation/gpio.txt

Now that all supported gpio_tlmm_config-using boards
are using gpiomux, remove the deprecated code.

1de238e0eb msm: add tlmm support for gpio.
GPIO support for Qualcomm SOCs requires interaction with the
radio (baseband processor). This API allows the different boards
to enable GPIO through the radio processor in a generic way.
