[PATCH v2 09/10] usb: musb: use io{read,write}*_rep accessors

[Will Deacon <will.deacon@arm.com>]

From: Matthew Leach <matthew@mattleach.net>

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 in the musb
accessors with io{read,write}{8,16,32}_rep calls instead.
