nissa: Invert the USB-A limit select
The output ilimit select should be inverted so that
the EC output is 1 when current limiting is enabled (SDP), and 0
when current limiting is disabled (CDP).
The default mode is CDP (charging downstream port), and
internally the EC assumes that setting an ilimit of 1 will enable
the higher current, so this value needs to be inverted before
setting the GPIO output.
