soc/intel/apollolake: add support for verstage
There previously was no support for building verstage on apollolake.
Add that suport by linking in the appropriate modules as well as
providing vboot_platform_is_resuming(). The link address for verstage
is the same as FSP-M because they would never be in CAR along side
each other. Additionally, program the ACPI I/O BAR and enable decoding
so sleep state can be determined for early firmware verification.
