soc/amd/common: Add GPIO config for native func w/ output drive
Our existing native function gpio configuration macro (PAD_NF) only sets
the pull. For PCIe reset, we now need to be able to set it to its
native function (PCIE_RST_L), and drive it low, then high.
BUG=b:182805349
TEST=Configure GPIO, see correct behavior.
