The "mss_top_scb" register region on PolarFire SoC contains many
different functions, including controls for the AXI bus and other things
mainly of interest to the bootloader. The interrupt register for the
system controller's mailbox is also in here, which is needed by the
operating system.

The ACSPCIE_PROXY_CTRL registers within the CTRL_MMR space of TI's J784S4
SoC are used to drive the reference clock to the PCIe Endpoint device via
the PAD IO Buffers. Add the compatible for allowing the PCIe driver to
obtain the regmap for the ACSPCIE_CTRL register within the System
Controller device-tree node in order to enable the PAD IO Buffers.

ASCPCIE_CTRL registers is available at:

Simple syscon nodes can be documented in common syscon.yaml, however
devices with simple-mfd compatible, thus with some children, should have
their own schema listing these children. Such listing makes the binding
specific, allows better validation (so the incorrect child would not
appear in the simple-mfd node) and actually enforces repeated rule for
simple-mfd devices:
"simple-mfd" is only for simple devices, where the children do not
depend on the parent.
Currently the syscon+simple-mfd binding is quite broad and allows
any child or property, thus above rule cannot be enforced.
Split the syscon.yaml binding into:
1. Common syscon properties, used potentially by many bindings.
2. Simple syscon devices (NO simple-mfd!).

Simple syscon devices may require deassertion of a reset signal in order
to access their register set. This change adds the `resets` property from
reset.yaml#/properties/resets (referenced through core.yaml), specifying
a maxItems of 1 for a single (optional) reset descriptor.
This will allow a future change to the syscon driver to implement reset
control.

The i.MX iomuxc-gpr bindings are undocumented and a mess. Drop their use
from the examples.
The problem with the binding beyond the just random variations is that
the iomuxc-gpr is not a separate block, but registers within the iomuxc
block containing random leftover controls. As a separate DT node, it
creates nodes with overlapping memory addresses.
