ARM: rmobile: Convert Porter to SPL
Due to size limitations of the MERAM, switch U-Boot to SPL.
The SPL is loaded by the SPI_LOADER into MERAM and then loads
U-Boot proper into DRAM. This way U-Boot can freely grow in
size in DRAM, as there is plenty of it.

NOTE: To update U-Boot, first install u-boot.img to 0x140000 in SPI NOR,
then use the Minimon to flash u-boot-spl.srec using ls,2,e6304000.
To generate u-boot-spl.srec, use objcopy:
arm-linux-gnueabi-objcopy -O srec spl/u-boot-spl u-boot-spl.srec
