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

Signed-off-by: Axel Lin axel.lin@gmail.com --- 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 )
