vc/amd/fsp/mendocino/FspmUpd: don't use pointers for usb_phy config
The size of a pointer changes between a 32 and 64 bit coreboot build. In order to be able to use a 32 bit FSP in a 64 bit coreboot build, change the pointer in the UPDs to a uint32_t to always have a 32 bit field in the UPD for this.
