[RESEND PATCH 3/4] mmc: mmci: use io{read,write}*_rep accessors instead of string functions
From: Will Deacon <hidden>

Subsystem:
arm primecell mmci pl180/1 driver, multimedia card (mmc), secure digital (sd) and sdio subsystem, the rest · Maintainers:
Russell King, Ulf Hansson, Linus Torvalds
The {read,write}s{b,w,l} operations are not defined by all architectures
and are being removed from the asm-generic/io.h interface.
This patch replaces the usage of these string functions with
io{read,write}{8,16,32}_rep calls instead, which are defined for all
architectures.
