Previously, some support for certain keys on the HP keyboard has been
added already in commit 3ee5447b2048 ("platform/x86: hp-wmi: Handle Omen
Key event"), however this as tested did not allow even the fn+esc key on
my HP Envy which uses the same keycode on my HP Envy x360 laptop to work
--the keycode rather than being passed in as a separate int from WMI, was
being passed in as the event_data for the HPWMI_OMEN_KEY event.
This patch, as tested was able to properly get the keycode for fn+esc,
and for fn+f12 which is supposed to be a programmable key according to
HP's keyboard diagram and is thus mapped to KEY_PROG2. The fn+f8 key
combination (mute microphone) was a standard HPWMI_BEZEL_BUTTON key,
however it did not previously have an entry in the sparse keymap. This
patch preserves the original HPWMI_OMEN_KEY behavior for laptops that
use it by only taking the keycode from the event_data only when the
event_data is nonzero.
