[PATCH v2] net: phy: spi_ks8995: add dependency on GPIO

[Sudip Mukherjee]

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

I'm going to apply Arnd's patch because it properly removes the
unnecessary linux/gpio.h include.

Thanks.

I think Arnd's patch is still not applied as we are still having build
failures for the implicit declarations. Or you want me to send v3 after
removing unnecessary linux/gpio.h include?

It's definitely there in net-next, commit 27090cbdc345cd5fd6f6e57a8986c504c27e4d23

Ohhh.. ok.. linux-next is still using net-next from next-20160217, I 
hope Monday it will be fine.
