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.

On S2MPG10 (and similar like S2MPG11), top-level interrupt status and
mask registers exist which need to be unmasked to get the PMIC
interrupts. This additional status doesn't seem to exist on other PMICs
in the S2MP* family, and the S2MPG10 driver is manually dealing with
masking and unmasking currently.
The correct approach here is to register this hierarchy as chained
interrupts, though, without any additional manual steps. Doing so will
also simplify addition of other, similar, PMICs (like S2MPG11) in the
future.
Update the driver to do just that.

The commit bf231e5feb ("mfd: sec-core: Add support for the Samsung
s2dos05") adding s2dos05 support didn't add anything related to IRQ
support, so I assume this works without IRQs.
Rather than printing a warning message in sec_irq_init() due to the
missing IRQ number, or returning an error due to a missing irq chip
regmap, just return early explicitly.
This will become particularly important once errors from sec_irq_init()
aren't ignored anymore in an upcoming patch and helps the reader of
this code while reasoning about what the intention might be here.

This driver misses to include some of the respective headers of some of
the APIs used. It also includes headers that aren't needed (e.g. due to
previous driver rework where includes weren't updated).
It is good practice to directly include all headers used, which avoids
implicit dependencies and spurious build breakage if someone rearranged
headers, as this could cause the implicit includes to be dropped.
Include the relevant headers explicitly and drop superfluous ones.

Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Samsung PMIC drivers are used only on Devicetree boards.
Additionally, the PMIC datasheets describe the interrupt line as active
low with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
Marek Szyprowski reports that together with DTS change (proper level in
DTS) it fixes RTC alarm failure that he observed from time to time on
TM2e board.

The main MFD driver for Samsung PMICs (S2MPSXX, S5M876X) used with
Exynos SoCs can be compiled and used as a module. The dependent clock,
regulator and RTC drivers already can be built as a module.
Building entire set of drivers as modules might require using initial
ramdisk and can make booting process longer (due to probe deferrals).
However adding such option is useful for testing and for multi-platform
configurations.
This also add required module authors to sec-irq.c file based on recent
main contributors.

The RTC on S2MPS11 is the same as S2MPS14. However interrupt numbers of
RTC alarms 0 and 1 were inversed between these two devices. So when
rtc-s5m driver requested S2MPS14_IRQ_RTCA0 interrupt, it matched to
S2MPS11_IRQ_RTCA1, not RTCA0.

BUILD_BUG_ON for future generations.
