media: drivers: media: pci: sta2x11: fix Kconfig dependency on GPIOLIB

When STA2X11_VIP is enabled, and GPIOLIB is disabled,
Kbuild gives the following warning:

WARNING: unmet direct dependencies detected for VIDEO_ADV7180
  Depends on [n]: MEDIA_SUPPORT [=y] && GPIOLIB [=n] && VIDEO_V4L2 [=y] && I2C [=y]
  Selected by [y]:
  - STA2X11_VIP [=y] && MEDIA_SUPPORT [=y] && MEDIA_PCI_SUPPORT [=y] && MEDIA_CAMERA_SUPPORT [=y] && PCI [=y] && VIDEO_V4L2 [=y] && VIRT_TO_BUS [=y] && I2C [=y] && (STA2X11 [=n] || COMPILE_TEST [=y]) && MEDIA_SUBDRV_AUTOSELECT [=y]

This is because STA2X11_VIP selects VIDEO_ADV7180
without selecting or depending on GPIOLIB,
despite VIDEO_ADV7180 depending on GPIOLIB.
