[ARM PATCH] 2170/1: OMAP update 2/8, take 2: Arch files

Patch from Tony Lindgren

This patch syncs the mainline kernel with the linux-omap tree.
The highlights of the patch are:
- Collapse OMAP 1610, 6912 and 1710 into one processor group 16xx
- USB updates by David Brownell
- Pin multiplexing updates by David Brownell
- Board specific low level serial port init
