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

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.
