[U-Boot] [U-Boot, v4, 02/66] spl: configure 'return to bootrom' separately for SPL and TPL

[Philipp Tomsich]

> On the RK3368, we want our TPL to use the 'return to bootrom' boot
> method (to have the bootrom load up the SPL stage) and then continue
> with different boot methods (MMC, SPI, etc.) from SPL.
> 
> This adds the config option needed to control the availabily of the
> 'return to bootrom' boot-method separately for the TPL stage.
