media: camif-core: Drop GPIO handling

Browse Source 
The driver and platform data refers to the legacy GPIO API,
doesn't really use it, and also calls some GPIO-related functions
passed as platform data.

This platform data is not used anywhere in the kernel.

I'm not outright deleting the driver, just deleting the bogus
GPIO handling. If outoftree developers want to fix up the
driver the GPIOs should be defined in some kind of firmware
node and be obtained using the gpiod_get*() APIs directly
in the driver, but I don't even know what these GPIOs are
since they are hidden in platform data that is not in the
mainline kernel, so what can I do.
