regulator: Switch i2c drivers back to use .probe()

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.

regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers between 5.10 and 5.15

This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS
for drivers that existed in 4.14") but changes regulators didn't exist
in Linux 5.10 but did exist in Linux 5.15.

regulator: pf8x00: Add suspend support

This patch adds suspend/resume support so that it is possible to
configure the LDOs and BUCKs as on or off during suspend phase as
well as to configure suspend specific voltages.

regulator: pf8x00: fix nxp,phase-shift

Fix the ternary condition which is a bad coding style
in the kernel

I also remove the defering configuration of the nxp,phase-shift.
The configuration is now done at parsing time. It save some memory
and it's better for comprehension.

I also use the OTP default configuration when the parameter is wrong
or not specified.
I think that it's better to use the default configuration from the chip
than an arbitrary value.

regulator: pf8x00: mark nxp,ilim-ma property as deprecated

This property seems useless because we can use the
regulator-max-microamp generic property to do the same
and using generic code.

As this property was already released in a kernel version,
we can't remove it, just mark it as deprecated.

regulator: pf8x00: Use specific compatible strings for devices

The pf8x00 driver supports three devices, the DT compatible strings
and I2C IDs should enumerate these specifically rather than using a
wildcard so that we don't collide with anything incompatible in the
same ID range in the future and so that we can handle any software
visible differences between the variants we find.
