rockchip: add option to change method of loading u-boot
If we would like to boot from SD card, we have to implement mmc driver
in SPL stage, and get a slightly large SPL binary. Rockchip SoC's
bootrom code has the ability to load spl and u-boot, then boot.
If CONFIG_ROCKCHIP_SPL_BACK_TO_BROM is enabled, the spl will return to
bootrom in board_init_f(), then bootrom loads u-boot binary.
Loading sequence after rework:
bootrom ==> spl ==> bootrom ==> u-boot

Fixed up spelling of U-Boot, boorom, opinion->option, Rochchip:
