This patch set updates Microchip PolarFire SoC Icicle Kit support
of RISC-V U-Boot.

The patches are based upon latest U-Boot tree
(https://source.denx.de/u-boot/u-boot) at commit id
d843273a8022e70ccbdb6ad446b3335c3753e84f

The memory device node is updated based on the latest FPGA reference
design v2022.10 and a small 4MB reservation is made at the end of 32-bit
DDR to provide some memory for the HSS to use, add Microchip QSPI driver.

Changes in v2:
- Add Co-developed-by with patch
- Replace spi-nand with flash in device node
- Add board details for QSPI NAND
- Rename QSPI driver file with microchip-coreqspi
- Add microchip,coreqspi-rtl-v2 to the compatible list
- Use MICROCHIP_COREQSPI instead of MICROCHIP_QSPI in kconfig
