[PATCH] Input: i8042 - add quirk for Acer Aspire Go 15 AG15-42P

[Chris Sommers]

On the Acer Aspire Go 15 (AG15-42P), the internal keyboard drops out
~5 seconds after boot on both Linux and Linux-LTS kernels. Keystrokes on
the built-in keyboard stop registering while the trackpad and external
keyboards remain functional.

Testing confirms that booting with the i8042.reset kernel parameter
resolves the issue and keeps the internal keyboard responsive.

Add SERIO_QUIRK_RESET_ALWAYS to i8042_dmi_quirk_table for the Acer
Aspire AG15-42P to automatically apply this quirk on boot.
