fix(usb_phy): Fixed USB PHY clock during low-power modes

Browse Source 
On ESP32-S3, USB PHY is clocked from BBPLL,
however if the BBPLL is not used as CPU clock source,
the power management unit can turn it off.
This commit registers USB as BBPLL consumer so it is not turned off.

Closes https://github.com/espressif/esp-idf/issues/15451
