Implement the init_cfg pad op in all imx-media subdevices. The try
formats are initialized to the current active formats on all pads.

Bitmask for the MIPI CSI-2 data PHY status doesn't seem to be correct.
Fix it.

Calling S_STREAM OFF multiple times on a video device is valid, although
dubious, practice. Instead of warning about it and setting stream count
lower than zero, just ignore the subsequent S_STREAM calls and correct
the stream count to zero.

Adds MIPI CSI-2 Receiver subdev driver. This subdev is required
for sensors with a MIPI CSI2 interface.
- Switch from the v4l2_of_ APIs to the v4l2_fwnode_ APIs.
- Add the function csi2ipu_gasket_init() to initialize the gasket at
s_power(ON). The gasket needs to be programmed with the correct color
component ordering to handle UYVY vs. YUYV ordered mbus formats from
sensors. Note that the description of the CSI2IPU_GASKET register in
the i.MX6 reference manual is wrong w.r.t bit 2 (the manual refers to
this register as CSI2_SW_RST): setting bit 2 selects YUYV order, not UYVY.
