[PATCH v2] powerpc: Move CONFIG_QE_GPIO to SoC

Commit 7aa1aa6ecec2 ("QE: Move QE from arch/powerpc to drivers/soc")
moved QE into drivers/soc including gpio.c but left CONFIG_QE_GPIO
in powerpc's Kconfig.

Move it to SoC as well as it is the only place it is used:

  drivers/soc/fsl/qe/Makefile:obj-$(CONFIG_QE_GPIO)       += gpio.o qe_ports_ic.o
  include/soc/fsl/qe/qe.h:#ifdef CONFIG_QE_GPIO
  include/soc/fsl/qe/qe.h:#endif /* CONFIG_QE_GPIO */

There is also a dependency in USB subsystem for CONFIG_USB_FHCI_HCD:

  drivers/usb/host/Kconfig:	depends on QE_GPIO && QUICC_ENGINE

Because that USB driver selects CONFIG_FSL_GTM which is specific to
powerpc, it has to depend on CONFIG_PPC.
