The S2MPG10 PMIC is a Power Management IC for mobile applications with
buck converters, various LDOs, power meters, RTC, clock outputs, and
additional GPIO interfaces.

It has 10 buck and 31 LDO rails. Several of these can either be
controlled via software (register writes) or via external signals, in
particular by:
    * one out of several input pins connected to a main processor's:
        * GPIO pins
        * other pins that are e.g. firmware- or power-domain-controlled
          without explicit driver intervention
    * a combination of input pins and register writes.

Control via input pins allows PMIC rails to be controlled by firmware,
e.g. during standby/suspend, or as part of power domain handling where
otherwise that would not be possible. Additionally toggling a pin is
faster than register writes, and it also allows the PMIC to ensure that
any necessary timing requirements between rails are respected
automatically if multiple rails are to be enabled or disabled quasi
simultaneously.

This commit implements support for all these rails and control
combinations.

Additional data needs to be stored for each regulator, e.g. the input
pin for external control, or a rail-specific ramp-rate for when
enabling a buck-rail. Therefore, probe() is updated slightly to make
that possible.

Note1: For an externally controlled rail, the regulator_ops provide an
empty ::enable() and no ::disable() implementations, even though Linux
can not enable the rail and one might think ::enable could be NULL.
Without ops->enable(), the regulator core will assume enabling such a
rail failed, though, and in turn never add a reference to its parent
(supplier) rail. Once a different (Linux-controlled) sibling (consumer)
rail on that same parent rail gets disabled, the parent gets disabled
(cutting power to the externally controlled rail although it should
stay on), and the system will misbehave.

Note2: While external control via input pins appears to exist on other
versions of this PMIC, there is more flexibility in this version, in
particular there is a selection of input pins to choose from for each
rail (which must therefore be configured accordingly if in use),
whereas other versions don't have this flexibility.

Add support for Samsung's S2MPG11 PMIC, which is a Power Management IC
for mobile applications with buck converters, various LDOs, power
meters, NTC thermistor inputs, and additional GPIO interfaces. It
typically complements an S2MPG10 PMIC in a main/sub configuration as
the sub-PMIC.

Like S2MPG10, communication is not via I2C, but via the Samsung ACPM
firmware.

While at it, we can also switch to asynchronous probe, which helps with
probe performance, as the drivers for s2mpg10 and s2mpg11 can probe in
parallel.

Note: The firmware uses the ACPM channel ID and the Speedy channel ID
to select the PMIC address. Since these are firmware properties, they
can not be retrieved from DT, but instead are deducted from the
compatible for now.

Bucks can reasonably be supplies for LDOs, but not the other way
around. Since rail registration is going to be ordered by 'enum
s2mpg10_regulators', it makes sense to specify bucks first, so that
during LDO registration it is more likely that the corresponding supply
is known already.

This can improve probe speed, as no unnecessary deferrals and retries
are required anymore.

Using a threaded interrupt without a dedicated primary handler mandates
the IRQF_ONESHOT flag to mask the interrupt source while the threaded
handler is active. Otherwise the interrupt can fire again before the
threaded handler had a chance to run.

Mark explained that this should not happen with this hardware since it
is a slow irqchip which is behind an I2C/ SPI bus but the IRQ-core will
refuse to accept such a handler.

Set IRQF_ONESHOT so the interrupt source is masked until the secondary
handler is done.

The TPS65214 PMIC variant has a LOCK_REG register that prevents writes to
nearly all registers when locked. Unlock the registers at probe time and
leave them unlocked permanently.

This approach is justified because:
- Register locking is very uncommon in typical system operation
- No code path is expected to lock the registers during runtime
- Adding a custom regmap write function would add overhead to every
  register write, including voltage changes triggered by CPU OPP
  transitions from the cpufreq governor which could happen quite
  frequently
