Subject: [PATCH v8 12/14] bus: mhi: ep: Add HAS_IOMEM || INDIRECT_IOMEM
 dependency

The symbol MHI_BUS_EP neither depends on HAS_IOMEM, nor on
INDIRECT_IOMEM. But, the function mhi_ep_ring_num_elems in
drivers/bus/mhi/ep/ring.c is using a IO memcpy operation. So, when
building for UM which doesn't have CONFIG_HAS_IOMEM=y, the build fails.
