New ASUS B650/B660/X670 boards firmware have not exposed WMI monitoring
GUID and entrypoint method WMBD could be implemented for different device
UID.
Implement the direct call to entrypoint method for monitoring the device
UID of B550/X570 boards.

have got a nct6775 chip, but by default there's no use of it
because of resource conflict with WMI method.
This commit adds such boards to the monitoring list with new ACPI device
UID.

This is a match function, which does not and should not return error/0
but a match result (true / false or 1/0), and it should be named
accordingly.

Please reduce the noise. Make this a debug message if you think you need it.

If this is an error, I expect the code to return an error and abort
the probe function. Otherwise make it a debug message. Also, even as
debug message this is misleading, because it suggests and error when
the result is really that the code uses direct access. There should
be something like "Using direct access" or "Accessing chip registers
directly" in the message.
