SPL: Move the omap SPL framework to common/spl 

Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL
framework, enable on all of the previously using boards.  We move the
spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/.  We leave
the NAND one in-place as we plan to replace it later in this series.

We use common/spl to avoid linker problems with respect to merging
constant strings in objects.   Otherwise all strings in common/ will be
linked in and kept which grows SPL in size too much.

CONFIG_SYS_SPL_MALLOC_SIZE
The size of the malloc pool used in SPL.
CONFIG_SPL_FRAMEWORK
Enable the SPL framework under common/. This framework
supports MMC, NAND and YMODEM loading of U-Boot and NAND
NAND loading of the Linux Kernel.
CONFIG_SPL_DISPLAY_PRINT
For ARM, enable an optional function to print more information
