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")

Log errors are the most widely used mechanism for reporting issues in
the kernel. When an error is logged using the device helpers, eg
dev_err(), it gets metadata attached that identifies the subsystem and
device where the message is coming from. Introduce a new test that makes
use of that metadata to report which devices logged errors (or more
critical messages).

Move the ksft python module, which provides generic helpers for
kselftests, to a common directory so it can be more easily shared
between different tests.

Move the discoverable devices test to a subdirectory to allow other
related tests to be added to the devices directory.

Introduce a new 'of-fullname-regex' property that takes a regular
expression and matches against the OF_FULLNAME property. It allows
matching controllers that don't have a unique DT address across sibling
controllers, and thus dt-mmio can't be used.
One particular example of where this is needed is on MT8195 which has
multiple USB controllers described by two level deep nodes and using the
ranges property:
ssusb2: usb@112a1000 {
reg = <0 0x112a1000 0 0x2dff>, <0 0x112a3e00 0 0x0100>;
ranges = <0 0 0 0x112a0000 0 0x3f00>;
xhci2: usb@0 {

Add support for a --boards-dir parameter through which the directory in
which the board files will be searched for can be specified. The
'boards' subdirectory is still used as default when the parameter is not
specified.
This allows more easily running the test with board files supplied by an
external repository like
https://github.com/kernelci/platform-test-parameters.

Add a new test to verify that a list of expected devices from
discoverable buses (ie USB, PCI) have been successfully instantiated and
probed by a driver.
The per-platform list of expected devices is selected from the ones
under the boards/ directory based on the DT compatible or the DMI IDs.
