ARM: OMAP2: Misc updates from linux-omap tree

Misc updates from linux-omap tree, mostly to update common
device initialization and add missing defines from linux-omap
tree. Also some changes to make room for adding 34xx in
following patches.

Note that the I2C resources are now set up in
arch/arm/plat-omap/i2c.c helper, and can be removed
from devices.c.
