Vlv2TbltDevicePkg/PlatformInitPei: Support USB init
In order to support recovery in PEI phase, a platform need initialize USB controller. This logic is missing in current PchInitPeim. We removed MultiPlatformInfoInit() because it is already done in PlatformEarlyInitEntry(). We also initialize XhciMemBaseAddr to 0, or it is garbage value.
