3f3527044d riscv: dts: fix the mpfs's reference clock frequency
The initial devicetree for PolarFire SoC incorrectly created a fixed
frequency clock in the devicetree to represent the msspll, but the
msspll is not a fixed frequency clock. The actual reference clock on a
board is either 125 or 100 MHz, 125 MHz in the case of the icicle kit.
Swap the incorrect representation of the msspll out for the actual
reference clock.

0b8e6f8411 riscv: dts: Add QSPI NAND device node
Add QSPI NAND device node to the Microchip PolarFire SoC
Icicle kit device tree.

The Winbond NAND flash memory can be connected to the
Icicle Kit by using the Mikroe Flash 5 click board and
the Pi 3 Click shield.

ab1644bdc4 riscv: dts: Update memory configuration
In the v2022.10 Icicle reference design, the seg registers have been
changed, resulting in a required change to the memory map.
A small 4MB reservation is made at the end of 32-bit DDR to provide some
memory for the HSS to use, so that it can cache its payload between
reboots of a specific context.

06142d6874 riscv: dts: Split Microchip device tree
The device tree split into .dtsi and .dts files, common
device node for eMMC/SD, enable I2C1, UART1 for console
instead of UART0, enable the DDR 2GB memory and in
that 288MB memory is reserved for fabric buffer.

e7bb113cc4 riscv: dts: mpfs-icicle-kit: Drop 'clock-frequency' in the uart nodes
The uart nodes already provide <clocks> property for the driver to
dynamically calculate the correct clock frequency. There is no need
to keep the hard-coded <clock-frequency> property.
