media: ipu3-cio2: Defer probing until the PMIC is fully setup
On devices where things are not fully describe in devicetree (1)
and where the code thus falls back to calling cio2_bridge_init(),
the i2c-clients for any VCMs also need to be instantiated manually.
The VCM can be probed by its driver as soon as the code instantiates
the i2c-client and this probing must not happen before the PMIC is
fully setup.
Make cio2_bridge_init() return -EPROBE_DEFER when the PMIC is not
fully-setup, deferring the probe of the ipu3-cio2 driver.
This is a preparation patch for adding VCM enumeration support to
the ipu3-cio2-bridge code.
1) Through embedding of devicetree info in the ACPI tables
