vboot: Fix S3 resume with stage_cache

In VBOOT_STARTS_IN_ROMSTAGE=y case, vboot_run_logic() did not
get called when postcar was loaded from TSEG stage cache on
ACPI S3 resume path. Resume failed as MP init attempts to
access microcode update from unverified FW_MAIN_A/B section.

In a similar fashion, for POSTCAR=n, loading ramstage from
TSEG stage cache would bypass the call to vboot_run_logic().

TEST=samsung/lumpy with VBOOT_STARTS_IN_ROMSTAGE=y is able
to complete S3 resume.
