2d64e3829b riscv: k210: Rename airam to aisram
This is more consistent with the naming of other ram banks, and matches
what Linux is doing.

2eebe5b373 riscv: Enable some devices pre-relocation
These devices are necessary for the clock driver, which is required by the
sram driver, to run pre-relocation.

This adds the necessary bindings. Most of them are already there.

237e5880f8 spi: dw: Add SoC-specific compatible strings
This adds SoC-specific compatible strings to all users of the designware
spi device. This will allow for the correct driver to be selected for each
device. Where it is publicly documented, a compatible string for the
specific device version has also been added. Devices without
publicly-documented device versions include MSCC SoCs, and Arc Socs. All
compatible strings except those for SoCFPGAs and some of the versioned
strings have been taken from Linux.

Since SSI_MAX_XFER_SIZE is determined at runtime, this is not strictly
necessary. However, it is a good cleanup and brings things closer to Linux.

963911e9e1 riscv: k210: Reduce DMA block size
Although the max DMA size supported by the hardware register is 22 bits (or
4M), the Linux driver for this device only supports transfers of up to 2M.
On a device with 8M total memory, I don't think it will make too much of a
difference.

e89e8983dc riscv: Update Kendryte device tree for new CLINT driver
The interrupt controller property is removed from the clint binding because
the clint is not an interrupt-controller. That is, no other devices have an
interrupt which is controlled by the clint.

bba8618c8e riscv: Add device tree for K210 and Sipeed Maix BitM
Where possible, I have tried to find compatible drivers based on the layout
of registers. However, many devices remain untested. All untested devices
have been left disabled, but some tentative properties (such as compatible
strings, and clocks, interrupts, and resets properties) have been added.
