AM33xx and BeagleBone support

AM33xx and BeagleBone support

[Jan Luebbe]

This is an updated series based on current master, with more cleanup from
Sascha's. Some of these patches should already be on next.

The CPSW driver is not yet intended for merging and included only for those
who want to try it out.

[PATCH 14/19] ARM omap hsmmc: Fix register offset

[Jan Luebbe]

From: Sascha Hauer <s.hauer@pengutronix.de>

The hsmmc module has a 0x100 offset in its register space. The real
register space size for the module is 4K, so when we register the
device with the size 4k, we have to account for the offset in the
driver, not in the resource allocation.

[PATCH 16/19] ARM OMAP AM33XX: create new ARCH for AM33xx

[Jan Luebbe]

From: Teresa Gámez <t.gamez@phytec.de>

Created ARCH for AM33xx boards as second stage bootloader.
This includes:
- Added dmtimer0
- Created basic header files
- Added MMC support for ARCH_AM33XX
- Added reset function

Signed-off-by: Teresa Gámez <t.gamez@phytec.de>

Some header file cleanup by:
