RISC-V: Remove CLINT related code from timer and arch Right now the RISC-V timer driver is convoluted to support: 1. Linux RISC-V S-mode (with MMU) where it will use TIME CSR for clocksource and SBI timer calls for clockevent device. 2. Linux RISC-V M-mode (without MMU) where it will use CLINT MMIO counter register for clocksource and CLINT MMIO compare register for clockevent device. We now have a separate CLINT timer driver which also provide CLINT based IPI operations so let's remove CLINT MMIO related code from arch/riscv directory and RISC-V timer driver.

riscv: Add Kendryte K210 SoC support Add support for the Kendryte K210 RISC-V SoC. For now, this support only provides a simple sysctl driver allowing to setup the CPU and uart clock. This support is enabled through the new Kconfig option SOC_KENDRYTE and defines the config option CONFIG_K210_SYSCTL to enable the K210 SoC sysctl driver compilation. The sysctl driver also registers an early SoC initialization function allowing enabling the general purpose use of the 2MB of SRAM normally reserved for the SoC AI engine. This initialization function is automatically called before the dt early initialization using the flat dt root node compatible property matching the value "kendryte,k210".

This enables support for Kendryte K210 SoC platform hardware.
riscv: K210: Add a built-in device tree The K210's bootloader does not provide a device tree. Give the ability to providea builtin one with the SOC_KENDRYTE_K210_BUILTIN_DTB option. If selected, this option result in the definition of a builtin DTB entry in the k210 sysctl driver. If defined, the builtin DTB entry points to the default k210.dts device tree file and is keyed with the vendor ID 0x4B5, the arch ID 0xE59889E6A5A04149 ("Canaan AI" in UTF-8 coded Chinese) and the impl ID 0x4D41495832303030 ("MAIX200"). These values are reported by the SiPEED MAIXDUINO board, the SiPEED MAIX Go board and the SiPEED Dan Dock board.

Builds a device tree for the Kendryte K210 into the Linux image.
This option should be selected if no bootloader is being used.
If unsure, say Y.
