The builds of allmodconfig of s390, m68k, tilegx, tilepro is failing
with the error:
 drivers/net/phy/spi_ks8995.c:477:3: error: implicit declaration of function 'gpiod_set_value'
 drivers/net/phy/spi_ks8995.c:477:19: error: implicit declaration of function 'gpio_to_desc'

GPIO is now used to reset the switch so we should have a dependency on
GPIOLIB. While adding the dependency also add COMPILE_TEST so that we
can build test it.

v2: added COMPILE_TEST and gpio/consumer.h
