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.

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.

k210: dts: add missing power bus clocks Linux drivers for many of the K210 peripherals depend on the power bus clock to be specified. Add the missing clocks and their names to avoid problems when booting Linux using u-boot DT.

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.
