https://bugzilla.tianocore.org/show_bug.cgi?id=4727 Recently some of XHCI host controllers require to have extra 1ms delay before accessing any MMIO register during reset. PHY transition from P3 to P0 can take around 1.3ms and the xHCI reset can take around 1.5ms. Add PCD to control the delay, the default is 2 ms.
