When CONFIG_VIDEO_ATOMISP_ISP2401 is disabled, clang warns:
./drivers/staging/media/atomisp//pci/isp2400_input_system_local.h:32:40:
error: redefinition of typedef 'input_system_cfg2400_t' is a C11 feature
[-Werror,-Wtypedef-redefinition]
typedef struct input_system_cfg2400_s input_system_cfg2400_t;
^
./drivers/staging/media/atomisp//pci/input_system_local.h:22:40: note:
previous definition is here
typedef struct input_system_cfg2400_s input_system_cfg2400_t;
^
1 error generated.
input_system_cfg2400_t's typedef was copied from
isp2400_input_system_local.h to input_system_local.h, rather than moved.
Remove the one in isp2400_input_system_local.h so that there is no more
warning, which can break the build under -Werror.

Some sensors come with a variable-focus lens where the lens focus is
controller by a VCM (Voice Coil Motor). If there is a VCM for the
lens-focus, and if so which one, is described on the vcm_type field
of the ACPI SSDB table.
These VCMs are a second I2C device listed as an extra I2cSerialBusV2
resource in the same ACPI device as the sensor. The i2c-core-acpi.c
code only instantiates an i2c-client for the first I2cSerialBusV2
resource.
Add support for instantiating an i2c-client for the VCM with
the type of the i2c-client set based on the SSDB vcm_type field.

Since cio2_bridge_init() may now return -EPROBE_DEFER it is best to
call it before anything else.

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.

Allwinner H6 has a Hantro G2 core used for VP9 decoding. It's not clear
at this time if HEVC is also supported or not.
