    arm64: dts: qcom: acer-aspire1: Correct audio codec definition
    
    [ 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.
