Subject: [PATCH v2 08/10] musb: tusb6010: use io{read,write}*_rep accessors

From: Matthew Leach <matthew@...tleach.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
tusb6010 accessors with io{read,write}{8,16,32}_rep calls instead.
