Subject: [PATCH 1/3] arm64: dts: ti: k3-am62p5-sk: Remove the unused config from USB1_DRVVBUS

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.
For that, either deep Sleep pullup can be selected or the pin can have the
same configuration that it had when SoC was in active mode.
In order for deep sleep configuration to take effect, the deep sleep
control bit has to be enabled.
Remove the deep sleep state configuration from USB1_DRVBUS pin as it is
anyways not taking effect (deep sleep control bit is not set).

This reverts commit 115290c112952db27009668aa7ae2f29920704f0.
