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

There is an implementation to run the CPU at full speed although it does
not seem to make much difference.

rockchip: Add support for Raxda Rock 2

This board includes an RK3288 SoC on a SOM. It can be mounted on a

So far this is verified to boot to a prompt from a microSD card. The serial
console works as well as HDMI.

Thanks to Tom Cubie for sending me a board.

rockchip: Drop first 32kb of zeros from the rkSD image type

Instead of creating a rockchip SPL SD card image with 32KB of zeros
which can be written to the start of an SD card, create the images with
only the useful data that should be written to an offset of 32KB on the
SD card.

The first 32 kilobytes aren't needed for bootup and only serve as
convenient way of accidentally obliterating your partition table.
