[PATCH 0/3][SRU][OEM-5.10] backlight parsing for VBT 234+

[AceLan Kao]

From: "Chia-Lin Kao (AceLan)" <acelan.kao at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/1912157

[Impact]
Current driver fails to parse VBT 234+ and gets wrong brightness levels.
It leads to screen dim completely when brightness is set to lowest.

[Fix]
We need the commits to parse VBT 234+
https://patchwork.freedesktop.org/patch/394304/

[Test]
Verified on Dell machines

[Where problems could occur]
The patches are simple and with a separate flow control for VBT 234,
should have no impact for current brightness control.
