drivers/mmc/fsl_esdhc.c: fix compiler warnings

Browse Source 
Commit 77c1458d caused the following compiler warnings:

fsl_esdhc.c: In function 'esdhc_pio_read_write':
fsl_esdhc.c:142: warning: assignment discards qualifiers from pointer target type
fsl_esdhc.c: In function 'esdhc_setup_data':
fsl_esdhc.c:169: warning: unused variable 'wml_value'
fsl_esdhc.c: In function 'esdhc_pio_read_write':
fsl_esdhc.c:164: warning: control reaches end of non-void function

Fix these.
