The driver depends on CONFIG_OF, so it is not necessary to use
of_match_ptr() here. We remove of_match_ptr() here.

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.

This commit reapplies commit 601e6d48ee35 ("mfd: rsmu_i2c: Convert to
i2c's .probe_new()") which was accidently reverted by commit
1b3b1d6c27cc ("mfd: rsmu: Support 32-bit address space").

Without this change the driver fails to build in combination with commit
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") which
is contained in v6.3-rc2.

Fixes: 1b3b1d6c27cc ("mfd: rsmu: Support 32-bit address space")

We used to assume 0x2010xxxx address. Now that we need to access
0x2011xxxx address, we need to support read/write the whole 32-bit
address space.

Also defined RSMU_MAX_WRITE_COUNT and RSMU_MAX_READ_COUNT for readability

.probe_new() doesn't get the i2c_device_id * parameter, so determine
that explicitly in the probe function.

<title>i2c: Make remove callback return void</title>

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.

Add support for ClockMatrix(TM) and 82P33xxx families of timing
and synchronization devices. The access interface can be either
SPI or I2C. Currently, it will create 2 types of MFD devices,
which are to be used by the corresponding rsmu character device
driver and the PTP hardware clock driver, respectively.
