Commit f2a8aa053c17 ("typec: tcpm: Represent source supply through
power_supply") moved the code to register a power_supply representing
the device supplying power to the type-C connector, from the fusb302
code to the generic tcpm code.
This has caused the power-supply registered by the fusb302 driver,
which determines how much current the bq24190 can draw, to change name
from "fusb302-typec-source" to "tcpm-source-psy-i2c-fusb302".

platform_device_id are not supposed to change at runtime. All functions
working with platform_device_id provided by <linux/platform_device.h>
work with const platform_device_id. So mark the non-const structs as
const.

Add device-properties to make the bq24292i charger connected to
the bus get its input-current-limit from the fusb302 Type-C port
controller which is used on boards with the cht-wc PMIC,
as well as regulator_init_data for the 5V boost converter on
the bq24292i.
Since this means we now hook-up the bq24292i to the fusb302 Type-C port
controller add a check for the ACPI device which instantiates the fusb302.

The structure cht_wc_i2c_adap_driver is local to the source
and does not need to be in global scope, so make it static.
Cleans up sparse warning:
symbol 'cht_wc_i2c_adap_driver' was not declared. Should it be static?

The Cherry Trail Whiskey Cove PMIC's IRQ line is attached to one of
the GPIOs of the Cherry Trail SoC. The CHT GPIO controller sometimes
fails to deliver IRQs (seen when there is an IRQ storm on another pin).
This commit works around this by reducing the long timeout which was
a poor attempt to workaround this from 3s to 30ms and after that
manually checking the status register for transfer completion by
calling the threaded IRQ handler directly.
This is safe todo as the entire threaded IRQ handler is protected
by a mutex.
Note 30ms should be more then long enough, at 100KHz any smbus single
byte transaction should be finished in 4ms.

Testing has shown that writing 1 to clear the read-complete irq does
not work until the data register has been read first.
This commit fixes the driver to read the data register first, halving the
amount of interrupts in most cases since we mostly read on this i2c bus.

Although unlikely without locking the smbux_xfer function may miss
the nack flag and further fixes in this patch-set add some more
complex constructions which need protection.

The Intel Cherry Trail Whiskey Cove PMIC does not contain a builtin
battery charger, instead boards with this PMIC use an external TI
bq24292i charger IC, which is connected to a SMBUS controller built into
the PMIC.
This commit adds an i2c-bus driver for the PMIC's builtin SMBUS
controller. The probe function for this i2c-bus will also register an
i2c-client for the TI bq24292i charger after the i2c-bus has been
registered.
Note that several device-properties are set on the client-device to
tell the bq24190 power-supply driver to integrate the Whiskey Cove PMIC
and e.g. use the PMIC's BC1.2 detection (through extcon) to determine
the maximum input current.
