Sometimes a system may have 2 input event nodes with the same name where
we only want to apply keyboard hwdb rules to 1 of the 2 devices.
This problem happens e.g. on devices where the soc_button_array driver is
used (e.g. intel atom based tablets) which registers 2 event nodes with
the name "gpio-keys".
This commit adds a new extended match rule which extends the match to also
check $attr{phys} and $attr{capabilities/ev}, allowing to differentiate
between devices with an identical name.
