mb/google/brya: Enable south XHCI ports 1 and 2
FSP v2081 has a bug where it uses the information about south XHCI
ports to enable TCSS XHCI ports. This change works around this bug by
enabling south XHCI ports 1 and 2 in brya baseboard devicetree. brya0
already enables south XHCI port 1 in overridetree.cb, however, it is
still enabled in baseboard/devicetree in case more variants are added
to brya before FSP is fixed.
BUG=b:184324979
TEST=Verified that TCSS XHCI ports 1 and 2 are now enabled.
