[PATCH 2/2] HID: apple: use the standard keyboard backlight LED name

[Andre Eikmeyer <dev@deq.rocks>]

The T2-attached butterfly keyboard backlight is exposed as
apple::kbd_backlight. This leaves the color field empty and gives
userspace a model-specific name for the same white keyboard-backlight
function exposed by Magic Keyboards.

Magic Keyboard backlight support was added later and already follows the
current LED naming convention. As a result, userspace has to handle two
different names for the same function.

We should use :white:kbd_backlight for both implementations. This follows
the LED color and function naming convention and lets userspace discover
either keyboard generation without a special case for the butterfly
models.
