[PATCH v2 3/3] arm64: dts: allwinner: a64: Add pinmux setting for CSI MCLK on PE1

[Jagan Teki <jagan@amarulasolutions.com>]

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.
