Some camera modules have the SoC feeding a master clock to the sensor
instead of having a standalone crystal. This clock signal is generated
from the clock control unit and output from the CSI MCLK function of
pin PE1.
Add a pinmux setting for it for camera sensors to reference.

Changes for v2:
- add /omit-if-no-ref/
- add pin name as csi-mclk-pin instead of csi-mclk
