[PATCH] platform/x86: hp-wmi: Ignore backlight and FnLock events

[Krishna Chomal]

On HP OmniBook 7 the keyboard backlight and FnLock keys are handled
directly by the firmware. However, they still trigger WMI events which
results in "Unknown key code" warnings in dmesg.

Add these key codes to the keymap with KE_IGNORE to silence the warnings
since no software action is needed.

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.
