In preparation for supporting ACPI probing, move DMI quirk handling
logic at the probe's top, to be able to return as quickly as possible in
case there is no DMI matching.
Additionally, simplify the code by replacing dmi_check_system() and
related callback with dmi_first_match(). While at it, also drop a few
unnecessary empty lines.
