This is a random set of cleanups, dead code removal and minor
optimizations.  This is a v2 of patchset sent long time ago, extended
with a couple more entries (one including a driver cleanup to enable
further changes). Tested on Tegra3 (ARM) and x86 devices.

v2:
 - added regulator_dev.reg_data cleanup patches
 - added a missing hunk in patch 6
 - removed an extra change from patch 5
 (Note: skipping changelogs in the patches, as the update has no relevant
  material changes there)
