Microchip's PolarFire SoC has a total of 9 contexts associated with the
Platform Interrupt controller (PLIC). the E51 core has a single context
(M Mode), and the application processor U54 cores have two each (M mode
and S mode, respectively)
While we are at it, there are a total of 186 interrupts, not 187.

Microchip's PolarFire SoC (device family name: MPFS) is not specific to
the Icicle Kit. Rename the devicetree sources to be more generic and to
align with Linux and allow for other development boards to adopt.

Define all the register offset directly in the driver according
to the RISCV PLIC specification as they are not configurable,
see: https://github.com/riscv/riscv-plic-spec.
Updated devicetrees that has PLIC accordingly.

This commit adds/modifies `riscv,isa` strings using the following rules:
* the ISA string is lowercase
* multi-letter extensions are preceded with the underscore mark
* if an extension is implied by another one, it is not specified - e.g. the
D extension implies the F extension, so writing `rv32ifd` is redundant

This commit moves the `mpfs-icicle.dtsi` file to a common `microchip`
directory and updates include paths in the `mpfs_icicle` board
devicetree.
