The edk2module provides various APIs to perform register read/write operations through python scripts using the Python UEFI interpreter on UEFI shell.

The current PCI read / write APIs allow only reading up to 4 bytes of data from the PCI configuration space. Need to add extended APIs to provide support for reading the full PCI and extended PCI configuration space.
