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. Signed-off-by: Tony Lindgren <tony@atomide.com>
