Subject: [PATCH 2/2] platform/x86: hp-wmi: Add support for Fn+P hotkey

From: Edip Hazuri <edip@...ip.dev>

Newer Hp Victus (And probably newer omen) e.g. Victus 16-s1011nt that i
own have a Fn+P shortcut intended to use with omen gaming hub for
changing the performance profile. see [1]

> hp_wmi: Unknown event_id - 27 - 0x7
Based on the dmesg warning. I found that the key have 27 as event_id and
0x7 as event_data (keycode). I implemented it in the driver and now
libinput can capture the event.

Tested On Victus 16-s1011nt (9Z791EA) with MB 8C9C
