ARM: dts: imx6qdl: Fix SPDIF regression
Commit 833f2cbf7091 ("ARM: dts: imx6: change the core clock of spdif")
changed many more clocks than only the SPDIF core clock as stated in
the commit message.
The MLB clock has been added and this causes SPDIF regression as
reported by Xavi Drudis Ferran and also in this forum post:
https://forum.digikey.com/thread/34240
The MX6Q Reference Manual does not mention that MLB is a clock related
to SPDIF, so change it back to a dummy clock to restore SPDIF
functionality.
Thanks to Ambika for providing the fix at:

This fix was correct, but overwritten by commit 833f2cbf7091099baee28136dc68678e974c0ac5.
MLB (Media Local Bus) Clock is in fact not related to SPDIF according to the MX6Q Reference
Manual. Tested playback and record on pulseaudio with 44.1kHz samples.
