Commit 961748bb1555 ("dt-bindings: mfd: rk8xx: Deprecate rockchip,system-
power-controller") made the property "rockchip,system-power-controller"
deprecated in favor of the shorter, universal form "system-power-controller".
Following the updates to the board dts files, [1] make the favored property
name checked first, to save a few CPU cycles.

This integrates RK816 support in the this existing rk8xx mfd driver.
This version has unaligned interrupt registers, which requires to define a
separate get_irq_reg callback for the regmap. Apart from that the
integration is straightforward and the existing structures can be used as
is. The initialization sequence has been taken from vendor kernel.

Process rise event last, to avoid stuck keys when multiple interrupts
are coalesced. This can happen typically when resuming from suspend
via power key press and holding the power button for a bit too short,
so that RISE an FALL IRQ flags are set before any interrupt routine
has a chance to run.
Input subsystem will interpret it as holding down a power key for
a long time, which leads to unintended initiation of shutdown UI
on some OSes.

Since commit 210f418f8ace ("mfd: rk8xx: Add rk806 support"), devices are
registered with "0" as id, causing devices to not have an automatic device id
and prevents having multiple RK8xx PMICs on the same system.
Properly pass PLATFORM_DEVID_AUTO to devm_mfd_add_devices() and since
it will ignore the cells .id with this special value, also cleanup
by removing all now ignored cells .id values.
Now we have the same behaviour as before rk806 introduction and rk806
retains the intended behavior.
This fixes a regression while booting the Odroid Go Ultra on v6.6.1:

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Add support for SPI connected rk806, which is used by the RK3588
evaluation boards. The PMIC is advertised to support I2C and SPI,
but the evaluation boards all use SPI. Thus only SPI support is
added here.

Simplify the device identification logic by supplying the relevant
information via of_match_data. This also removes the dev_info()
printing the chip version, since that's supplied by the match data
now.
Due to lack of hardware this change is compile-tested only.
