ARM64: dts: keep hub control signals reset pull state
RESET and CONNECT come out of reset with pull downs enabled. Keep
that in the pin muxing.
These pins are switched to output during the hub configuration and then
controlled as needed. The datasheet specifically states that CONNECT
must not be driven when RESET is low, so keeping the pull downs is
less likely to violate the spec.
The INT pin has an external pull up, so keeping the pull down makes
the system draw more power.
