[PATCH 12/14] mmc: tmio_mmc_core: Replace kmap_atomic() with kmap_local_page()

[Adrian Hunter <adrian.hunter@intel.com>]

kmap_local_page() is equivalent to kmap_atomic() except that it does not
disable page faults or preemption. Where possible kmap_local_page() is
preferred to kmap_atomic() - refer kernel highmem documentation.

In this case, there is no need to disable page faults or preemption, so
replace kmap_atomic() with kmap_local_page(), and, correspondingly,
kunmap_atomic() with kunmap_local().
