Victor Sun 2197f4306a HV: Add acpi_fixup api to override acpi on needs
Add acpi_fixup() api in bsp that can override platform ACPI info when
do init_bsp(), this is useful when platform bootloader is not lock
down before production.

In current code only the wake vector addresses would be parsed after
boot and then override to host_acpi_info, we can add more in furture
based on our needs.

Tracked-On: #1264
