[PATCH] platform/x86: asus-nb-wmi: map ProArt key (0x8b) to KEY_PROG3

[Nizar Al-Kabbani <nizar.m.kabbani@gmail.com>]

The dedicated "ProArt" key on the ASUS ProArt PX13 (HN7306) emits ASUS
WMI event code 0x8b. This code is absent from the asus-nb-wmi sparse
keymap, so pressing the key only produces a "Unknown key code 0x8b"
message and does nothing in userspace.

On this model the key is exposed solely through the WMI interface and has
no HID scancode, so it can only be handled inside asus-nb-wmi. Map 0x8b
to KEY_PROG3 so the key emits a bindable event, consistent with the
existing KEY_PROG3 mapping used for the ASUS programmable/Armoury key.
