arch/x86: fix cmos post logging in non romcc bootblock

cmos_post_init() is called in src/arch/x86/bootblock_simple.c, and
that function is reponsible for bootstrapping the cmos post register
contents. Without this function being called none of the cmos post
functionality works correctly. Therefore, add a call to lib/bootblock.c
which the C_ENVIRONMENT_BOOTBLOCK SoCs use.
