Stephen Warren 4850ab9a4f tegra2: Fix conflicting pinmux for UARTA
Tegra appears to boot with function UARTA pre-selected on mux
group SDB. If two mux groups are both set to the same function,
it's unclear which group's pins drive the RX signals into the
HW module. For UARTA, SDB certainly overrides group IRTX in
practice. To solve this, configure some alternative function on
SDB to avoid the conflict. Also, tri-state the group to avoid
driving any signal onto it until we know what's connected.
