msm: gpio: move gpio driver to platform driver
Add support for platform driver, so that the irq's used for handling the
gpios can be taken using the resources[] from device file.
This will eliminate the dependency on cpu_is_xxx() checks during the
registering the IRQ's and will help in the single binary support for
7x27a and 8625.
