[PATCH] Abolish cpu_read* and cpu_write* accessors

[Masahiro Yamada]

Commit 2e6a88f2101d (add cpu native ordered io accessors) introduced
these macros and then commit be57f20cdd7d (Fix big endian MMIO
primitives) figured out they are equivalent to __raw_{read,write}*.

They turned out unnecessary after all.  Anyway, most source files
use __raw_read* and __raw_write*.

Let's replace a few remaining references and abolish them.
