riscv: dts: microchip: update peripherals in icicle kit device tree
Assorted minor changes to the MPFS/Icicle kit device tree:
- enable mmuart4 instead of mmuart0
- remove sifive pdma
- split memory node to match updated fpga design
- move stdout path to serial1 to avoid collision with
bootloader running on the e51
