[PATCH v2 2/3] platform/x86: asus-nb-wmi: add fnlock_use_hid quirk for ProArt P16

[Marcus Grenängen]

The ASUS ProArt P16 (N-Key keyboard 0B05:19B6) advertises the WMI fn-lock
DEVID (0x00100023) as present via DSTS, but the DEVS call has no effect.
Fn-lock must instead be toggled via a HID feature report sent to the N-Key
keyboard (handled by hid-asus).

Add a fnlock_use_hid flag to struct quirk_entry and set it for the ProArt
P16 via a DMI match on DMI_PRODUCT_FAMILY. This flag is consumed by
asus-armoury to select the HID path instead of WMI DEVS.
