Input: i8042 - merge quirk tables

Browse Source 
[ Upstream commit ff946268a0813c35b790dfbe07c3bfaa7bfb869c ]

Merge i8042 quirk tables to reduce code duplication for devices that need
more than one quirk. Before every quirk had its own table with devices
needing that quirk. If a new quirk needed to be added a new table had to
be created. When a device needed multiple quirks, it appeared in multiple
tables. Now only one table called i8042_dmi_quirk_table exists. In it every
device has one entry and required quirks are coded in the .driver_data
field of the struct dmi_system_id used by this table. Multiple quirks for
one device can be applied by bitwise-or of the new SERIO_QUIRK_* defines.

Also align quirkable options with command line parameters and make vendor
wide quirks per device overwriteable on a per device basis. The first match
is honored while following matches are ignored. So when a vendor wide quirk
is defined in the table, a device can inserted before and therefore
ignoring the vendor wide define.
