net: phy: spi_ks8995: include linux/gpio/consumer.h

The ks8995 phy driver just started using gpiod_* functions, which are
declared in linux/gpio/consumer.h, not linux/gpio.h, resulting in a
build failure in randconfig builds that do not have CONFIG_GPIOLIB
enabled:

drivers/net/phy/spi_ks8995.c: In function 'ks8995_probe':
drivers/net/phy/spi_ks8995.c:477:3: error: implicit declaration of function 'gpiod_set_value' [-Werror=implicit-function-declaration]

This changes the header inclusion so it builds in all configurations.
