After being asked to not depend on ARCH_QCOM* or similar,
unsurprisingly compilation fails on UM as it has no I/O
memory:

drivers/built-in.o: In function `qcom_ebi2_probe':
>> drivers/bus/qcom-ebi2.c:333: undefined reference to
   `devm_ioremap_resource'

Fix this by letting the Kconfig atleast depend on HAS_IOMEM.
