Insert raw strings to prevent Python3 from interpreting string literals as Unicode strings and "\d" as invalid escaped sequence.
Fix the warnings:
tools/testing/selftests/devices/probe/test_discoverable_devices.py:48: SyntaxWarning: invalid escape sequence '\d' usb_controller_sysfs_dir = "usb[\d]+"
tools/testing/selftests/devices/probe/test_discoverable_devices.py: 94: SyntaxWarning: invalid escape sequence '\d' re_usb_version = re.compile("PRODUCT=.*/(\d)/.*")
Fixes: dacf1d7a78bf ("kselftest: Add test to verify probe of devices from discoverable buses")
