Guennadi Liakhovetski 69d1fe18e9 mmc: tmio: only access registers above 0xff, if available
Not all tmio implementations have registers above oxff. Accessing
them on thise platforms is dangerous. In some cases it leads to
address wrapping to addresses below 0x100, which corrupts random
unrelated registers.
