gpio: Avoid kernel.h inclusion where it's possible

Browse source 
Inclusion of kernel.h increases the mess with the header dependencies.
Avoid kernel.h inclusion where it's possible.

Besides that, clean up a bit other inclusions inside GPIO subsystem headers.
It includes:
 - removal pin control bits (forward declaration and header) from linux/gpio.h
 - removal of.h from asm-generic/gpio.h
 - use of explicit headers in gpio/consumer.h
 - add FIXME note with regard to gpio.h inclusion in of_gpio,h
