spl: configure 'return to bootrom' separately for SPL and TPL

Browse Source 
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.

Some platforms (e.g. the Rockchip RK3368) provide support in their
ROM for loading the next boot-stage after performing basic setup
from the TPL stage.
Enable this option, to return to the BOOTROM through the
BOOT_DEVICE_BOOTROM (or fall-through to the next boot device in the
boot device list, if not implemented for a given board)
