security/vboot: Removed vboot_prepare from vboot_locator
When prog_locate() is called in the stage VBOOT is starting from and the
image to be loaded is not the target image vboot_prepare() may be called
too early.
To prevent this vboot_prepare() is removed from the vboot_locator
structure. This allows more control over the start of the vboot logic.
To clarify the change the vboot_prepare() has been renamed to
vboot_run_logic() and calls to initialize vboot have been added at the
following places:
postcar_loader: when VBOOT starts in ROMSTAGE
romstage_loader: when VBOOT starts in BOOTBLOCK
ramstage_loader: when VBOOT starts in ROMSTAGE
BUG=N/A
TEST=tested on facebook fbg1701
