platform/x86: panasonic-laptop: filter out duplicate volume up/down/mute keypresses
On some Panasonic models the volume up/down/mute keypresses get
reported both through the Panasonic ACPI HKEY interface as well as
through the atkbd device.
Filter out the atkbd scan-codes for these to avoid reporting presses
twice.
Note normally we would leave the filtering of these to userspace by mapping
the scan-codes to KEY_UNKNOWN through /lib/udev/hwdb.d/60-keyboard.hwdb.
However in this case that would cause regressions since we were filtering
the Panasonic ACPI HKEY events before, so filter these in the kernel.
