Enabling this driver on top of my v2 arm64 gxbb series, I get:

  CC      drivers/mmc/host/meson-mmc.o
drivers/mmc/host/meson-mmc.c: In function 'meson_mmc_probe':
drivers/mmc/host/meson-mmc.c:471:12: error: implicit declaration of
function 'devm_pinctrl_get' [-Werror=implicit-function-declaration]
  pinctrl = devm_pinctrl_get(&pdev->dev);
            ^
drivers/mmc/host/meson-mmc.c:471:10: warning: assignment makes pointer

  pinctrl = devm_pinctrl_get(&pdev->dev);
          ^
cc1: some warnings being treated as errors

Either this is missing a Kconfig dependency on PINCTRL, or should be
using #ifdef CONFIG_PINCTRL or some other guard.

For gxbb we could just ignore this in the hopes that Nicolas will have a
working pinctrl driver soon, but it might reappear for COMPILE_TEST.

Regards,
Andreas
