Merge branch 'gma500-fixes' of git://github.com/patjak/drm-gma500 into drm-fixes

Patrik writes:
Two fixes for memory leaks split into Cedarview and Poulsbo versions,
and a fix for properly setting the pipe base when using fbdev. It's on
my todo-list to start unifying the chips since they are very similar,
but until then I'd like to split them up in case there are side-effects
on Cedarview that I cannot currently test.

airled: Verified pull from github matches what I expected.
