mmc: tmio-mmc: fix bad pointer math
commit 9c284c41c0886f09e75c323a16278b6d353b0b4a upstream.
The existing code gives an incorrect pointer value.
The buffer pointer 'buf' was of type unsigned short *, and 'count' was a
number in bytes. A cast of buf should have been used.
However, instead of casting, just change the code to use u32 pointers.
