[U-Boot] [PATCH 1/2] rockchip: add CONFIG_SPL_ROCKCHIP_SERIAL

[Lin Huang]

we can use this config to disable rockchip serial driver in SPL stage,
since some rockchip soc sram size is small(rk3036 etc), so we don't
want rockchip serial driver build in SPL, but we still want use common
debug driver in SPL.
