x86: samus: Add a target to boot through TPL

Browse source 
Add a version of samus which supports booting from TPL to SPL and then
to U-Boot. This allows TPL to select from an A or B SPL to support
verified boot with field upgrade.

bool "Chromebook samus booting from TPL"
help
This is a version of Samus which boots into TPL, then to SPL and
U-Boot proper. This is useful where verified boot must select
between different A/B versions of SPL/U-Boot, to allow upgrading of
almost all U-Boot code in the field.
