The Pixel 3 features two front-facing Sony IMX355 sensors with
different focal lengths (standard and wide-angle).
Both sensors are connected via CSIPHY1 and controlled over CCI I2C1,
using MCLK2 as the clock source. Describe the camera nodes and
associated resources in the device tree.
This enables support for the dual front camera configuration.

Currently I working on a patch which add 24 MHz to imx355, so this may not be
necessary.
Please wait with merging, after the patch gets tested also on Pixel 3a, I'll
send it :)
