soc/amd/picasso: Add driver for handling PCIE GPP bridges
This change adds a driver pcie_gpp.c which provides device_operations
for external and internal PCIe GPP bridges. These device operations
include standard PCI bridge operations as well as operations for
generating ACPI node for the device and returning appropriate ACPI
name for it.
