[v2,00/17] Update the Icicle Kit device tree

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 as many "DT compatible string <x> appears
un-documented" errors as possible.

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 (mmc) that are
already in linux/riscv/for-next.

Also depends on Geert's format changes to interrupt grouping etc [2].

Additionally, the interrupt-extended warnings on the plic/clint are 
cleared by [3] & [4], which lore appears to have been very confused about.

Right, it ended up being even more messier than I thought, and confuses
"b4 am" too.
I will resend these 3 series later today.
