Put the PPI configuration retriveal into an own library. That will allow to reuse the code in the UefipayloadPkg, where the firmware provides the ACPI tables, like QEMU does on OvmfPkg. However one major difference is that the PPI interface in UefiPayloadPkg is not backed by a MMIO device, but resides in DRAM and is shared with ACPI code. Add an additional parameter to provide the location of the PPI and test if the memory region has the correct attributes. Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com>
