The Image Signal Processor found on Cherry Trail devices is brought up in
D0 state on devices which have camera sensors attached to it. The ISP will
not enter D3 state again without some massaging of its registers beforehand
and the ISP not being in D3 state blocks the SoC from entering S0ix modes.

There was a driver for the ISP in drivers/staging but that got removed
again because it never worked. It does not seem likely that a real
driver for the ISP will be added to the mainline kernel anytime soon.

This commit adds a dummy driver which contains the necessary magic from
the staging driver to powerdown the ISP, so that Cherry Trail devices where
the ISP is used will properly use S0ix modes when suspended.

Together with other recent S0ix related fixes this allows S0ix modes to
be entered on e.g. a Chuwi Hi8 Pro and a HP x2 210.

Thanks for your work in this area. I still remember the first linux

On systems with ACPI instantiated i2c-clients, normally there is 1 fw_node
per i2c-device and that fw-node contains 1 I2cSerialBus resource for that 1
i2c-device.

But in some rare cases the manufacturer has decided to describe multiple
i2c-devices in a single ACPI fwnode with multiple I2cSerialBus resources.

An earlier attempt to fix this in the i2c-core resulted in a lot of extra
code to support this corner-case.

This commit introduces a new i2c-multi-instantiate driver which fixes this
in a different way. This new driver can be built as a module which will
only loaded on affected systems.

This driver will instantiate a new i2c-client per I2cSerialBus resource,
using the driver_data from the acpi_device_id it is binding to to tell it
which chip-type (and optional irq-resource) to use when instantiating.

Note this driver depends on a platform device being instantiated for the
ACPI fwnode, see the i2c_multi_instantiate_ids list of ACPI device-ids in
drivers/acpi/scan.c: acpi_device_enumeration_by_parent().
