sh: add romImage MMCIF boot for sh7724 and Ecovec V2
This patch is V2 of the MMCIF romImage boot support for sh7724 and the Ecovec board. With this patch applied and CONFIG_ROMIMAGE_MMCIF selected the romImage kernel image can be written to a MMC card and booted directly by the sh7724 cpu.

+ Say Y here to include experimental MMCIF loading code in
+ romImage. With this enabled it is possible to write the romImage
+ kernel image to an MMC card and boot the kernel straight from
+ the reset vector. At reset the processor Mask ROM will load the
+ first part of the romImage which in turn loads the rest the kernel
+ image to RAM using the MMCIF hardware block.
