[ARM] 3142/1: OMAP 2/5: Update files common to omap1 and omap2

Patch from Tony Lindgren

This patch syncs the mainline kernel with linux-omap tree.
The highlights of the patch are:

- Serial port and framebuffer init improvments by Imre Deak

- Common omap pin mux framework by Tony Lindgren

- Common omap clock framework by Tony Lindren
