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".
