I rolled up two small changes to the wm1811 audio codec config here:

- Dropped incorrect interrupt parent - GPX3-6 is the headset key GPIO,
  and does not seem to be the interrupt parent like on Midas (downstream
  calls it GPIO_HDMI_CEC on Midas, whereas for Tab 3 it's
  GPIO_EAR_SEND_END, so they definitely serve different functions).

- Added the MCLK2 clock as specified in the schematics, to more
  accurately describe the hardware.

I included them here since the whole patch modifies properties related
to audio (this section is what "fix some other small issues with the
sound setup" in the commit message refers to), but I can split it up
into a separate commit if it's necessary.

Best regards
