[PATCH v1 1/2] rockchip: configs: mk808: change CONFIG_TPL_TEXT_BASE

[Johan Jonker]

Currently the Rockchip rk3066a u-boot-tpl.bin file needs
to add the characters "RK30", while the other SoCs replace
the first 4 bytes. Bring this in line with the rest by
lowering CONFIG_TPL_TEXT_BASE and update rockchip.rst
instructions.
