Update extcon for v5.8
Detailed description for this pull request:
1. Update extcon provider driver
- Fix an error handling code by using devm_iio_channel_get() for extcon-adc-jac.c
- Fix the usage counter imbalance of runtime PM for extcon-arizona.c.
- Add proper dt-compatible string for extcon-max14577.c.
2. Update extcon core with minor updates:
- Remove unneeded initialization of local variable in extcon_register_notifier

extcon: remove redundant assignment to variable idx
When arizona_request_irq() returns an error code, a
pairing runtime PM usage counter decrement is needed
to keep the counter balanced. For error paths after
this function, things are the same.
Also, remove calls to pm_runtime_disable() when
pm_runtime_enable() has not been executed.

Add device tree compatible strings and create proper modalias structures
to let this driver load automatically if compiled as module, because
max14577 MFD driver creates MFD cells with such compatible strings.

In some error handling paths, a call to 'iio_channel_get()' is not balanced
by a corresponding call to 'iio_channel_release()'.
This can be achieved easily by using the devm_ variant of
'iio_channel_get()'.
This has the extra benefit to simplify the remove function.

The variable idx is being initialized with a value that is never read
and it is being updated later with a new value. The initialization is
redundant and can be removed.

Add enable regulators to dev_pm_opp_set_regulators() and disable
regulators to dev_pm_opp_put_regulators(). Even if bootloader
leaves regulators enabled, they should be enabled in kernel in
order to increase the reference count.

In addition to clocks and regulators, some devices can scale the bandwidth
of their on-chip interconnect - for example between CPU and DDR memory. Add
support for that, so that platforms which support it can make use of it.

When we read the OPP keys, it would be nice to do some sanity checks
of the values we get from DT and see if they match with the information
that is populated in the OPP table. Let's pass a pointer of the table,
so that we can do some validation.
