Could you clarify whether this replaces an existing quirk
or renders unnecessary the introduction of a new quirk,
because that decides whether this patch must go into stable.


Neither :)

This patch will simplify the quirk Mediatek wants to include in their patchseries.

After this patch the TD size part of the mediatek quirk can be reduced to maybe
a couple lines in total.
Yet another version of the Mediatek patcheries will be needed after this, but it will
be 50 - 100 lines shorter.

This patch is basically just code refactoring, enabling easier quirking.

It seems I need to do some rewording of the commit message of this patch as well
