V2: Halt HC at EndOfPei. Update the EhciPei driver to consume IOMMU_PPI to allocate DMA buffer. If no IOMMU_PPI exists, this driver still calls PEI service to allocate DMA buffer, with assumption that DRAM==DMA.

# The EhcPeim driver is responsible for managing EHCI host controller at PEI phase.
|
|
#
|
|
# It produces gPeiUsb2HostControllerPpiGuid based on gPeiUsbControllerPpiGuid
|
|
# which is used to enable recovery function from USB Drivers.
