This reverts commit 487970e8bb776c989013bb59d6cbb22e45b9afc6.
Updated bspec and workaround database note Wa_1409120013 is not needed
for DG2 (or any Display 13) platform.
This should probably say "Xe_LPD" to use standard terminology.

When adding new workarounds lately I've been dropping the platform
trailers since it's obvious enough from the next few lines of code (and
it's easy for the comments to get out of sync with the code). I'd be
tempted to just shorten this to "/* Wa_1409120013 */" but up to you.
if (IS_TIGERLAKE(dev_priv) || IS_ROCKETLAKE(dev_priv) ||
- IS_ALDERLAKE_S(dev_priv) || IS_DG1(dev_priv) || IS_DG2(dev_priv))
+ IS_ALDERLAKE_S(dev_priv) || IS_DG1(dev_priv))
We could also go with
if (DISPLAY_VER(dev_priv) == 12)
to simplify.
indeed, that is better. I will send a new version.
thanks

Anway, both of the code suggestions are optional; up to you whether you
think they're worth incorporating or not.
