init.common.usb.rc: Do not hardcode sys.usb.controller property

Upstream commit eb9b7bfd5954 ("arm64: dts: qcom: Harmonize DWC
USB3 DT nodes name") (v5.14-rc1) changed the DTS USB node names,
breaking the sys.usb.controller property hardcoded in the
platfrom specific init.usb.common.rc

This script will get rid of the static/hardcoded proprty name
and set the property to the available on-board USB controller
from /sys/class/udc instead.
