Kernel build bot reported a compilation error after the commit

  f626d6dfb709 ("gpio: of: Break out OF-only code"):

drivers/gpio/gpiolib-devres.o: In function `devm_gpiod_get_from_of_node':
gpiolib-devres.c:(.text+0x19a): undefined reference to `gpiod_get_from_of_node'

This happens due to move the latter under umbrella of CONFIG_OF_GPIO while
customer.h contains staled data.

Fix it by reshuffling contents of consumer.h to satisfy build dependencies.
