......................................................................

Add first BIOS block in coreboot.pre

This change ensures that the binary containing metadata hash anchor is
added before any file is added to CBFS. This will allow to verify all
the CBFS files that are not excluded from verification.

BUG=b:227809919
TEST=Build and boot to OS in Skyrim with CBFS verification enabled using
x86 and PSP verstages.
