Paul Burton da61fa5f42 mmc: don't support write & erase for SPL builds 
For SPL builds this is just dead code since we'll only need to read.
Eliminating it results in a significant size reduction for the SPL
binary, which may be critical for certain platforms where the binary
size is highly constrained.
