ARM: 6237/1: mmci: use sg_miter API to fix multi-page sg handling

The mmci driver's SG list iteration logic assumes that each SG entry
spans only one page, and only maps and flushes one page of the sg.  This
is not a valid assumption.  Fix it by converting the driver to the
sg_miter API, which correctly handles sgs which span multiple pages.
