mb/amd/birman/devicetree_phoenix: update USB PHY settings 

Update the initial USB PHY tuning values that were a copy of the ones
from the Chausie mainboard to the values used in the Birman UEFI
firmware reference implementation. The USB3 PHY tuning values are still
the same while some of the USB2 PHY tuning values are different. The
last two USB2 PHYs that are used by the USB4 controllers have a
different parameter set compared to the other USB2 PHYs.

TEST=All USB ports on Birman function as expected.
