powerpc/kcsan: Memory barriers semantics

Annotate memory barriers *mb() with calls to kcsan_mb(), signaling to
compilers supporting KCSAN that the respective memory barrier has been
issued. Rename memory barrier *mb() to __*mb() to opt in for
asm-generic/barrier.h to generate the respective *mb() macro.
