Merge tag 'regmap-fix-v4.5-big-endian' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap fix from Mark Brown:
 "A single revert back to v4.4 endianness handling.

  Commit 29bb45f25ff3 ("regmap-mmio: Use native endianness for
  read/write") attempted to fix some long standing bugs in the MMIO
  implementation for big endian systems caused by duplicate byte
  swapping in both regmap and readl()/writel().  Sadly the fix makes
  things worse rather than better, so revert it for now"
