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.
