[PATCH] platform/x86: pcengines-apu2 needs gpiolib

[Arnd Bergmann <arnd@xxxxxxxx>]

I ran into another build issue in randconfig testing for this driver,
when CONFIG_GPIOLIB is not set:

WARNING: unmet direct dependencies detected for GPIO_AMD_FCH
  Depends on [n]: GPIOLIB [=n] && HAS_IOMEM [=y]
  Selected by [y]:
  - PCENGINES_APU2 [=y] && X86 [=y] && X86_PLATFORM_DEVICES [=y] && INPUT [=y] && INPUT_KEYBOARD [=y] && LEDS_CLASS [=y]

WARNING: unmet direct dependencies detected for KEYBOARD_GPIO_POLLED
  Depends on [n]: !UML && INPUT [=y] && INPUT_KEYBOARD [=y] && GPIOLIB [=n]
  Selected by [y]:
  - PCENGINES_APU2 [=y] && X86 [=y] && X86_PLATFORM_DEVICES [=y] && INPUT [=y] && INPUT_KEYBOARD [=y] && LEDS_CLASS [=y]

Make the 'select' statements conditional on that so we don't have to
introduce another 'select'.

Fixes: f8eb0235f659 ("x86: pcengines apuv2 gpio/leds/keys platform driver")
Fixes: a422bf11bdb4 ("platform/x86: fix PCENGINES_APU2 Kconfig warning")
