After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("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.

Use the managed `devm_of_clk_add_hw_provider()` instead of
`of_clk_add_hw_provider()`.
This makes sure the provider gets automatically removed on unbind and
allows to completely eliminate the drivers `remove()` callback.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

As part of the ongoing i2c transition to the simple probe
("probe_new"), this patch uses i2c_match_id to retrieve the
driver_data for the probed device. The id parameter is thus no longer
necessary and the simple probe can be used instead.

Recalling NVM data into RAM during probe() initiates a re-calibration of
the clock. If the clock is already in-use, the recall operation can cause
a glitch on the frequency out. At power on, the factory data are loaded
from NVM into RAM by default. If the clock frequency has been changed
since power on, the recall operation can be used to re-initialize the clock
to factory setting.

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.
