x86: Add support for starting from SPL/TPL
When a previous phase of U-Boot has run we need to adjust the init of
subsequent states to avoid messing up the CPU state.
Add a new version of the start logic for SPL, when it boots from TPL
(start_from tpl.c) and a new version for U-Boot when it boots from SPL.
