[PATCH v3 01/11] leds: aw200xx: fix write to DIM parameter

[Dmitry Rokosov <ddrokosov@salutedevices.com>]

From: Martin Kurbanov <mmkurbanov@salutedevices.com>

If write only DIM value to the page 4, LED brightness will not be
updated, as both DIM and FADE need to be written to the page 4.
Therefore, write DIM to the page 1.
