Subject: [PATCH v9 2/3] mfd: Kconfig: MFD_SUN4I_GPADC depends on !TOUCHSCREN_SUN4I_GPADC

MFD_SUN4I_GPADC and TOUCHSCREEN_SUN4I are incompatible (both are drivers
for Allwinner SoCs' ADC). This makes sure TOUCHSCREEN_SUN4I isn't
enabled while MFD_SUN4I_GPADC is enabled.

added in v8. I wrongly put the XOR dependance for SUN4I_GPADC and
TOUCHSCREEN_SUN4I instead of for MFD_SUN4I_GPADC and TOUCHSCREEN_SUN4I.
