[PATCH 3/7] staging,spear_adc: Add dependency on HAS_IOMEM

[Richard Weinberger]

On archs like S390 or um this driver cannot build nor work.
Make it depend on HAS_IOMEM to bypass build failures.

drivers/staging/iio/adc/spear_adc.c: In function âspear_adc_probeâ:
drivers/staging/iio/adc/spear_adc.c:393:2: error: implicit declaration of function âiounmapâ [-Werror=implicit-function-declaration
