ACPI: video: Drop backlight_device_get_by_type() call from acpi_video_get_backlight_type()
All x86/ACPI kms drivers which register native/BACKLIGHT_RAW type
backlight devices call acpi_video_backlight_use_native() now. This sets
__acpi_video_get_backlight_type()'s internal static native_available flag.
This makes the backlight_device_get_by_type(BACKLIGHT_RAW) check
unnecessary.
Relying on the cached native_available value not only is simpler, it will
also work correctly in cases where then native backlight registration was
skipped because of acpi_video_backlight_use_native() returning false.
