[ARM] 3031/1: fix typos in comments of mmc.h

Patch from Erik Hovland

I noticed that the same typo (i before c in associated) showed up twice
in the file kernel/include/linux/mmc/mmc.h.

This patch fixes both of the instances I found with this mistake. The
typos are in comments and should have no affect on working code.
