[PATCH] PCI: amlogic: fix build failure due to missing linux/gpio/consumer.h header

[Corentin Labbe]

When building on x86, I got the following build failure:
drivers/pci/controller/dwc/pci-meson.c: In function âmeson_pcie_assert_resetâ:
drivers/pci/controller/dwc/pci-meson.c:290:2: error: implicit declaration of function âgpiod_set_value_cansleepâ; did you mean âgpio_set_value_cansleepâ? [-Werror=implicit-function-declaration]
  gpiod_set_value_cansleep(mp->reset_gpio, 0);
  ^~~~~~~~~~~~~~~~~~~~~~~~
  gpio_set_value_cansleep
drivers/pci/controller/dwc/pci-meson.c: In function âmeson_pcie_probeâ:
drivers/pci/controller/dwc/pci-meson.c:540:19: error: implicit declaration of function âdevm_gpiod_getâ; did you mean âdevm_gpio_freeâ? [-Werror=implicit-function-declaration]
  mp->reset_gpio = devm_gpiod_get(dev, "reset", GPIOD_OUT_LOW);
                   ^~~~~~~~~~~~~~
                   devm_gpio_free
drivers/pci/controller/dwc/pci-meson.c:540:48: error: âGPIOD_OUT_LOWâ undeclared (first use in this function); did you mean âGPIOF_INIT_LOWâ?
  mp->reset_gpio = devm_gpiod_get(dev, "reset", GPIOD_OUT_LOW);
                                                ^~~~~~~~~~~~~
                                                GPIOF_INIT_LOW

This is due to the missing linux/gpio/consumer.h header
