Update the Icicle Kit device tree

From: Conor Dooley <[email protected]>

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 for the device tree 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 v6:
- Dropped i2c patch, as its in i2c-next
- Added ack on gpio, reviewed-by on rtc
- Dropped child nodes from sysctrl binding entirely, added a link to the online documenation for the services the system controller can provide
- Dropped the #pwm-cells and replaced with a ref, a la Krzysztof's series

Changes from v5:
- reworded the descriptions in the pwm binding to (hopefully) add clarity
- added -mask to the custom properties and made them 32 bit
- renamed the i2c binding to corei2c, since it is not mpfs specific
- removed the child nodes of the system controller in example/dts & will create them in the driver.
@Rob, I assume keeping them documented is the correct thing to do?
- removed the dependancy on the clock binding from the examples
- reformatted rtc interrupts as per Rob's suggestion

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)
