There is nothing in the driver requires OF_GPIO. Moreover, driver
supports ACPI and OF_GPIO may be a quite overhead on such configurations.
Drop dependency for good and replace of_gpio.h to of.h since we have
one function to be defined from there.

Allow driver to be built with COMPILE_TEST for better test coverage.

There is no need to have an additional check to call
acpi_gpiochip_request_interrupts(). Even without any interrupts available
the registered ACPI Event handlers can be useful for debugging purposes.
