vboot2: separate verstage from bootblock
With CONFIG_RETURN_FROM_VERSTAGE false, the verstage loads the romstage over
the bootblock, then exits to the romstage. this is necessary for some SOC
(e.g. tegra124) which runs the bootblock on a different architecture.
With CONFIG_RETURN_FROM_VERSTAGE true, the verstage returns to the bootblock.
Then, the bootblock loads the romstage over the verstage and exits to the
romstage. this is probably necessary for some SOC (e.g. rockchip) which does not
have SRAM big enough to fit the verstage and the romstage at the same time.
BUG=none
TEST=Built Blaze with USE=+/-vboot2. Ran faft on Blaze.

Note: This purposefully is probably broken in vendorcode/google/chromeos
as I'm just trying to set a base for dropping more patches in. The vboot
paths will have to change from how they are currently constructed.
