Subject: [PATCH] hid-asus: Disable OOBE mode on the ProArt P16

The new ASUS ProArt 16" laptop series come with their keyboards stuck in
an Out-Of-Box-Experience mode. While in this mode most functions will
not work such as LED control or Fn key combos. The correct init sequence
is now done to disable this OOBE.

This patch addresses only the ProArt series so far and it is unknown if
there may be others, in which case a new quirk may be required.
