[U-Boot] [U-Boot, v4, 04/66] rockchip: back-to-bootrom: split BACK_TO_BOOTROM for TPL/SPL

[Philipp Tomsich]

> The back-to-bootrom option is rather unfortunately named
>   CONFIG_ROCKCHIP_SPL_BACK_TO_BOOTROM
> instead of
>   CONFIG_SPL_ROCKCHIP_BACK_TO_BOOTROM
> 
> To make is selectable through CONFIG_IS_ENABLED(ROCKCHIP_BACK_TO_BOOTROM),
> we need to rename it.  At the same time, we introduce a TPL_ variant of
> the option to give us finer-grained control over when it should be used.
> 
> This change is motivated by our RK3368 boot process, which returns to
> the boot ROM only from the TPL stage, but not from the SPL stage.
