[Letux-kernel] [PATCH] dt: gta04: fix polarity of clocks for mcbsp4

Will merge into next Letux release and test a little.

The Si4721 problem seems to be different. But may also need a fix in the
audio-card.

Yes! It is missing entries like

simple-audio-card,bitclock-master = <&bt_link_master>;

So maybe there is simply no clock...

Thanks and BR,
Nikolaus
