amd/stoneyridge: Add USB settings to gnvs

A later patch will rely on two USB settings from the BIOS.  Add these
to the global_gnvs_t structure.

The first is a data that will be used to locate the xHCI firmware for
reloading after a resume.  Although the existing calculations will be
somewhat simple, keeping this on the coreboot side will help in the
event multiple FWs are eventually in the build.

The second item is a usable EHCI base address that may be programmed
during S3 suspend and resume.  At the time the PTS and WAK code runs,
the BAR will be clear.

BUG=b:77602074
