The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.

While renaming one of the fields in the driver data struct, the kerneldoc
was not updated which apparently angers the test robot now.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

By convention platform_data refers to structures passed to drivers by
code that registers devices. When talking about model-specific data
structures associated with OF compatibles, we usually call them chip_data.
In order to avoid confusion rename all mentions of platform_data to
chip_data.

Dialog semiconductors SLG7XL45106 is an 8-bit I2C GPO expander.
The output port is controlled by a data byte with register
address. Add a compatible string for the same. Also update
the driver to write and read from it.

The PCA9571 very similar to the PCA9570, it only differs in the
number of GPIOs.
