Subject: viafb: remove LVDS initialization
From: Florian Tobias Schandinat <FlorianSchandinat@xxxxxx>
At least for VX800 this initialization is not very good as some parts of
the register are written with reserved values. This makes the display go
white in some configurations and not usable until the framebuffer is
removed. It's better to not initialize it as it allows to use a
previously (by BIOS) correctly configured display.
This patch makes some displays work but might cause problems on others.
This is bad but can not be easily avoided. If this causes some
regressions it's probably the best to fix it in the 'active' display setup
code.
