This patch series brings together patches [1] and [2] which
introduce mclk0 clock source via DT.

mclk0..3 are the four clock sources options
of SAI's clock MUX.=20

mclk0 option selects:
 - Bus Clock on i.MX8
 - MCLK1 on i.MX6/7

Finally we also update the DT binding information for SAI clocks.

In [1] and [2] Nicolin had a very good point on the fact that
mclk0 might not be needed in the DT. Anyhow, there are two reasons
for which I think mlck0 should be added to DT:

1) SAI clock source select MUX is really part of the hardware
2) flexibility! We let DT tell us which is the option for MUX
option 0.
