[PATCH v5 00/12] Update the Icicle Kit device tree

[conor.dooley at microchip.com]

From: Conor Dooley <conor.dooley at 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 binding (on clk/next) 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 [1] & [2].

Changes from v4:
- dont include icicle_kit_defconfig, accidentally added in v3
- drop prescaler from mpfs-rtc & calculate the value instead
- use corei2c as a fallback device for mpfs-i2c
- drop spi dt-binding (on spi-next)
  commit 2da187304e556ac59cf2dacb323cc78ded988169
- drop usb dt-binding (on usb-next)

Changes from v3:
- drop "mailbox: change mailbox-mpfs compatible string", already upstream:
  commit f10b1fc0161cd99e ("mailbox: change mailbox-mpfs compatible string")
- fix copy paste error in microchip,mpfs-mailbox dt-binding
- remove whitespace in syscontroller dt entry

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)
