Virupax Sadashivpetimath f4ebcab360 gpio: Handle stmpe-gpio platform data with no gpio base
This patch removes the requirement that gpio base be supplied in
platform data.

Wolfram Sang b8e9cf0b28 gpio: Add bitmask to block requests to unavailable stmpe GPIOs
GPIOs on these controller are multi-functional. If you decided to use
some of them e.g. as input channels for the ADC, you surely don't want
those pins to be reassigned as simple GPIOs (which may be triggered even
from userspace via 'export'). Same for the touchscreen controller pins.
Since knowledge about the hardware is needed to decide which GPIOs to
reserve, let this bitmask be inside platform_data and provide some
defines to assist potential users.
