[PATCH v5 00/10] PolarFire SoC dt for 5.19

Hey all,
Got a few PolarFire SoC device tree related changes here for 5.19.

Firstly, patches 1 & 2 of this series supersede [0] & are unchanged
compared to that submission, figured it would just be easier to keep
all the changes in one series.

As discussed on irc, patch 3 removes the duplicated "microchip" from
the device tree files so that they follow a soc-board.dts & a
soc{,-fabric}.dtsi format.

Patch 5 makes the fabric dtsi board specific by renaming the file to
mpfs-icicle-kit-fabric.dtsi & including it in the dts rather than
mpfs.dtsi. Additionally this will allow other boards to define their
own reference fabric design. A revision specific compatible, added in
patch 4, is added to the dt also.

The remainder of the series adds a bare minimum devicetree for the
Sundance Polarberry.

Thanks,
Conor.

Changes since v4:
- Whitespace and status ordering changes in the polarberry dt pointed
out by Heiko
- A new patch for same whitspace and status order changes, but applied
to the icicle dt
- A reordering of the icicle dt alphabetically to match the formatting
of the polarberry dt

Changes since v3:
- remove an extra line of wshitespace added to dt-binding
- remove unneeded "okay" status & sort status to node end
- sort polarberry dts entries in ~alphabetical order
- add a comment explaining why the second mac (mac0) is disabled on
polarberry

Changes since v2:
- make ,icicle-reference compatible with ,mpfs & put it inside the enum

Changes since v1:
- fixed whitespace problems in the polarberry dts
- disabled mac0 for the polarberry as its port is on the optional
carrier board
