ASoC: Make wm1250-ev1 depends on GPIOLIB

I got below build error if GPIO support is disabled. Make wm1250-ev1 depends on GPIOLIB to fix below build error.

I got the build error while trying to build for SND_MFLD_MACHINE and SND_SST_PLATFORM. ( "Enable ALSA for SoC audio support" and "Build all ASoC CODEC drivers" on X86 )

If platforms aren't using the standard gpiolib infrastructure they should keep their GPIO API implementation up to date with the current state of the art.
