U-Boot MMC SPL for OMAP4

This series adds mmc SPL support for OMAP4. This is essentially an up-streaming effort for TI's x-loader for OMAP4 using the SPL framework

This work partly draws upon previous work done for x-loader by:
Santosh Shilimkar<[email protected]> Rajendra Nayak<[email protected]>
and many others

Features supported:
* Clock init - DPLL locking, clock domains/modules enabling
* SDRAM/DMM initialization
* Mux initialization
* MMC raw read support
* MMC FAT read support

Improvments over x-loader:
* Code completely revamped
* DPLL programming that works for all SYS_CLK frequencies
* Automatic SDRAM identification and initialization
* Board dependent parts(especially mux) deferred to u-boot. So, same SPL will work for Panda and SDP and most likely on any other board that comes along
* Determination of u-boot size to avoid reading extra content while loading U-Boot
* Modular apporach to enable future addition of support for all OMAP3/4 platforms
