arm64: dts: ti: k3-am62p5-sk: Support SoC wakeup using USB1 wakeup

After the SoC has entered the Deep Sleep mode, USB1 can be used to wakeup
the SoC based on USB events triggered by USB devices. This requires that
the pin corresponding to the Type-A connector remains pulled up even after
the SoC has entered the Deep Sleep mode. Hence, enable Deep Sleep pullup /
pulldown selection for the USB1_DRVBUS pin and set its Deep Sleep state to
PULL_UP.
