platform/x86: panasonic-laptop: Use acpi_video_get_backlight_type()



Use acpi_video_get_backlight_type() to determine if we should register
the panasonic specific backlight interface. To avoid registering this
on systems where the ACPI or GPU native backlight control methods
should be used instead.
