Merge tag 'omap-cleanup-sparseirq-for-v3.7' into devel-dt

This branch contains changes needed to make omap2+
work properly with sparse IRQ. It also removes
dependencies to mach/hardware.h. These help moving
things towards ARM single zImage support.

This branch is based on a commit in tty-next
branch with omap-devel-gpmc-fixed-for-v3.7 and
cleanup-omap-tags-for-v3.7 merged in to keep things
compiling and sort out some merge conflicts.
