mfd: Add base driver for qnap-mcu devices

These microcontroller units are used in network-attached-storage devices
made by QNAP and provide additional functionality to the system.

This adds the base driver that implements the serial protocol via
serdev and additionally hooks into the poweroff handlers to turn
off the parts of the system not supplied by the general PMIC.

Turning off (at least the TSx33 devices using Rockchip SoCs) consists of
two separate actions. Turning off the MCU alone does not turn off the main
SoC and turning off only the SoC/PMIC does not turn off the hard-drives.
Also if the MCU is not turned off, the system also won't start again until
it is unplugged from power.

So on shutdown the MCU needs to be turned off separately before the
main PMIC.

The protocol spoken by the MCU is sadly not documented, but was
obtained by listening to the chatter on the serial port, as thankfully
the "hal_app" program from QNAPs firmware allows triggering all/most
MCU actions from the command line.

The implementation of how to talk to the serial device got some
inspiration from the rave-sp servdev driver.

mfd: pm8008: Rework to match new DT binding

Rework the pm8008 driver to match the new devicetree binding which no
longer describes internal details like interrupts and register offsets
(including which of the two consecutive I2C addresses the registers
belong to).

Instead make the interrupt controller implementation internal and pass
interrupts to the subdrivers using MFD cell resources.

Note that subdrivers may either get their resources, like register block
offsets, from the parent MFD or this can be included in the subdrivers
directly.

In the current implementation, the temperature alarm driver is generic
enough to just get its base address and alarm interrupt from the parent
driver, which already uses this information to implement the interrupt
controller.

The regulator driver, however, needs additional information like parent
supplies and regulator characteristics so in that case it is easier to
just augment its table with the regulator register base addresses.

Similarly, the current GPIO driver already holds the number of pins and
that lookup table can therefore also be extended with register offsets.

Note that subdrivers can now access the two regmaps by name, even if the
primary regmap is registered last so that it is returned by default when
no name is provided in lookups.

Finally, note that the temperature alarm and GPIO subdrivers need some
minor rework before they can be used with non-SPMI devices like the
PM8008. The temperature alarm MFD cell name specifically uses a "qpnp"
rather than "spmi" prefix to prevent binding until the driver has been
updated.
