baytrail: use MCRX in iosf access functions

While most registers accesses don't need the use of the MCRX
    register (upper 24 bits of address) the MCRX register should
    be protected. The reference code could be doing accesses to
    registers that initialized the MCRX register. Thus, any access
    after that should ensure the MCRX register is initialized
    appropriately.

BUG=None
    BRANCH=None
    TEST=Verified assembly output. Also, built and booted through
         depthcharge.
