[PATCH 1/4] ARM: OMAP2+: raw read and write endian fix

From: Victor Kamensky victor.kamensky@linaro.org

All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode.

Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.
