From: Conor Dooley <conor.dooley@microchip.com>

This series updates the Microchip Icicle Kit device tree by adding a
host of peripherals, and some updates to the memory map. In addition,
the device tree has been split into a third part, which contains "soft"
peripherals that are in the fpga fabric.

Several of the entries are for peripherals that have not get had their
drivers upstreamed, so in those cases the dt bindings are included where
appropriate in order to avoid the many "DT compatible string <x> appears
un-documented" errors.

Depends on mpfs clock driver series [1] to provide:
dt-bindings/clock/microchip,mpfs-clock.h
and on the other changes to the icicle/mpfs device tree from geert
that are already in linux/riscv/for-next.

Additionally, the interrupt-extended warnings on the plic/clint are 
cleared by [2] & [3].

[1] https://lore.kernel.org/linux-clk/20211216140022.16146-1-conor.dooley@microchip.com/T/
[2] https://lore.kernel.org/linux-riscv/cover.1639744468.git.geert@linux-m68k.org/
[3] https://lore.kernel.org/linux-riscv/cover.1639744106.git.geert@linux-m68k.org/

Changes from v2:
- dropped plic int header & corresponding defines in dts{,i}
- use $ref to drmode in mpfs-musb binding
- split changes to dts{,i} again: functional changes to existing
  elements now are in a new patch
- drop num-cs property in mpfs-spi binding
- dont make the system controller a simple-mfd
- move the separate bindings for rng/generic system services into the 
  system controller binding
- added an instance corei2c as i2c2 in the fabric dtsi
- add version numbering to corepwm and corei2c compat string (-rtl-vN)

Example is wrong, should read "microchip,mpfs-mailbox".

Will resubmit Monday.
