6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nikita Travkin <nikita@xxxxxxx>
[ Upstream commit feec9f0add432a867f23e29afcd2f7088889b8e2 ]
When initially added, a mistake was made in the definition of the codec.
Despite the fact that the DMIC line is connected on the side of the
codec chip, and relevant passive components, including 0-ohm resistors
connecting the dmics, are present, the dmic line is still cut in
another place on the board, which was overlooked.
Correct this by replacing the dmic configuration with a comment
describing this hardware detail.
While at it, also add missing regulators definitions. This is not a
functional change as all the relevant regulators were already added via
the other rail supplies.
