usb: musb: use io{read,write}*_rep accessors
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.
