Currently audio mclk uses a fixed clk of 11.2896MHz (multiple of 44.1kHz).
Replace this fixed clk with the programmable versa3 clk that can provide
the clocking to support both 44.1kHz (with a clock of 11.2896MHz) and
48kHz (with a clock of 12.2880MHz), based on audio sampling rate for
playback and record.

v1->v2:
 * Made Versa3 clock mapping as per HW manual and updated clocks
   property in codec_dai.
 * Replaced the node xtal->x1-clock and label x1_x2->x1 as x2 is a
   different crystal.
 * Updated clock-frequency = <400000> for i2c0 node in RZ/G2UL SMARC EVK.

Thanks for the update!

I'm a bit confused by the version and the changelog.
This is the second v2, and apparently there were also two v1s...

Gr{oetje,eeting}s,

As you said, it should be v4.

I will resend as v4 with fixing change log.

v4:
