Hi,

I want to add a new BSP for RISC-V-based Microchip PolarFire SoC(MPFS)
to RTEMS.

The PolarFire SoC is the 4x 64-bit RISC-V U54 cores and a 64-bit RISC-
V 
E51 monitor core SoC from Microchip.

The new BSP is added for the U54 cores not for E51 because the E51
moniter core is resreved for first stage bootloader (Hart Software
Services).

This BSP supports below components:

    4 CPU Cores (U54)
    Interrupt controller (PLIC)
    Timer (CLINT)
    UART (mmuart, 16550-compatible)

We have already done some work on this and tested but not with latest
RTEMS source(8th March, 2022 commit) and want to send patches with
latest source.
