mb/amd/birman/devicetree_phoenix_opensil: add stub MPIO chips

Add the stub MPIO chips that contain the PCIe engine configuration for
the external PCIe interfaces to the devicetree. Birman's
port_descriptors_phoenix.c was used as a reference. The static
configuration in the devicetree assumes that the default WLAN0_WWAN0 is
selected; for the other cases we'll still need to fix up things
accordingly in the mutable devicetree. The WLAN01 and WWAN01 cases still
need to be handled in a follow-up patch. Since openSIL currently doesn't
use the info from the gpio_group struct element, but deasserts both PCIe
reset pins GPIO 26 and 27, the gpio_group isn't specified in the chip
configuration in the devicetree.
