hw/ufs: Fix potential bugs in MMIO read|write
This patch fixes two points reported in coverity scan report [1]. Check
the MMIO access address with (addr + size), not just with the start offset
addr to make sure that the requested memory access not to exceed the
actual register region. We also updated (uint8_t *) to (uint32_t *) to
represent we are accessing the MMIO registers by dword-sized only.
