[PATCH v2 1/5] PCI: aardvark: Fix compilation on s390

[Pali Rohár]

Include linux/gpio/consumer.h instead of linux/gpio.h, as is said in the
latter file.

This was reported by kernel test bot when compiling for s390.

  drivers/pci/controller/pci-aardvark.c:350:2: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror,-Wimplicit-function-declaration]
  drivers/pci/controller/pci-aardvark.c:1074:21: error: implicit declaration of function 'devm_gpiod_get_from_of_node' [-Werror,-Wimplicit-function-declaration]
  drivers/pci/controller/pci-aardvark.c:1076:14: error: use of undeclared identifier 'GPIOD_OUT_LOW'
