Actually pmic_arb_base_write has the writel_relaxed inside it.
that's why we removed the __raw_writel to use the common function.
Anyways, we drop the renaming patch from this patch series.

__raw_writel() is there on purpose because we're reading bytes at
a time and the CPU could be big-endian or little-endian.
readl_relaxed() would do a byte swap which we don't want.
ok. Thanks for clarifying it. We do not remove the __raw_writel.
