ARM: at91: replace __raw_{readl, writel} of peripherals with readl, writel
Use the potentially endianness-changing readl, writel and siblings
directly. They looks prettier and are the correct thing to do, as
even if the CPU is in big-endian mode, the peripherals are little-endian.
Unlike Linux, barebox readl,writel are the same Linux'
{readl,writel}_relaxed (they don't imply memory barriers)
and thus there shouldn't be any functional change.
Patch was generated by a mass search and replace. I looked it over,
adjust some whitespace and further verified by reviewing the output of
git diff HEAD~1 --word-diff | \
perl -pe 's/\[-(.*?)__raw_/{+$1/; s/-\]\{\+/+}{+/;' \
-e 's/(\{\+.*?\+\})\1/__ALL_IS_WELL__/' | grep '+}{+'
which filters out the common case of lines where a single
__raw_{readT,writeT} had its __raw_ prefix stripped without any
further changes.
