It sounds like you could just put LCDControl & 0x2e in the DT rather
than using values such as 0x100..0x107, which don't appear to match the
register format you mentioned above.

No.  Platforms which route the outputs to something like VGA or HDMI can
change the framebuffer format.  Your suggestions is far too restrictive.

Surely the DT should describe the HW setup only. Usually, a particular
HW setup can support multiple different framebuffer formats. Hence, the
DT wouldn't/shouldn't imply anything about the framebuffer format, but
simply which wires are connected to the LCD.
