arm64: dts: ti: k3-am62x-sk-common: Remove the unused cfg in USB1_DRVVBUS

Browse Source 
After the SoC has entered the DeepSleep low power 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 DeepSleep low power
mode.
For that, either DeepSleep pullup configuration can be selected or the pin
can have the same configuration that it had when SoC was in active mode.
Remove the unnecessary DeepSleep state configuration from USB1_DRVBUS pin,
as the DeepSleep control bit is not set and the active configuration is
sufficient to keep the pin pulled up. This simplifies the setup and removes
redundant configuration.

This reverts commit 527f884d2d.
