[PATCH] usb: dwc3: qcom: Don't leave BCR asserted

[Krishna Kurapati]

Leaving the USB BCR asserted prevents the associated GDSC to turn on. This
blocks any subsequent attempts of probing the device, e.g. after a probe
deferral, with the following showing in the log:

[    1.332226] usb30_prim_gdsc status stuck at 'off'

Leave the BCR deasserted when exiting the driver to avoid this issue.
