[PATCH] Vlv2TbltDevicePkg/PlatformInitPei: Support USB init

[Jiewen Yao]

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.
