[PATCH 3/5] net: rfkill-gpio: Add explicit include for of.h

[Rob Herring]

With linux/acpi.h no longer implicitly including of.h, add an explicit
include of of.h to fix the following error:

net/rfkill/rfkill-gpio.c:181:21: error: implicit declaration of function 'of_match_ptr' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
