Hooray for generic fbdev support, making this a oneliner. We just
needed to fix preferred_depth fixed and the vmap support added first.
This is useful for testing fbdev testcases in igt. Right now we only
have a simple one in the fbdev testcases, which passes both info and
mmap subtests.

This adds support for the TDO TL070WSH30 TFT-LCD panel module.
The panel has a 1024×600 resolution and uses 24 bit RGB per pixel.
It provides a MIPI DSI interface to the host, a built-in LED backlight
and touch controller.

>From the code, we see that DRM_ERROR is just an error log print

On some panels hooked up to the ti-sn65dsi86 bridge chip we found that
link training was failing. Specifically, we'd see:
ti_sn65dsi86 2-002d: [drm:ti_sn_bridge_enable] *ERROR* Link training failed, link is off (-5)
The panel was hooked up to a logic analyzer and it was found that, as
part of link training, the bridge chip was writing a 0x1 to DPCD
address 00600h and the panel responded NACK. As can be seen in header
files, the write of 0x1 to DPCD address 0x600h means we were trying to
write the value DP_SET_POWER_D0 to the register DP_SET_POWER. The
panel vendor says that a NACK in this case is not unexpected and means
"not ready, try again".
In testing, we found that this panel would respond with a NACK in
about 1/25 times. Adding the retry logic worked fine and the most
number of tries needed was 3. Just to be safe, we'll add 10 tries
here and we'll add a little blurb to the logs if we ever need more
than 5.
