soc: riscv32: add RV32M1 SoC as openisa_rv32m1 The OpenISA RV32M1 SoC has four CPU cores. Two of these are RISC-V 32-bit cores, which are named "RI5CY" and "ZERO-RISCY". (The other two cores are ARM Cortex-M0+ and -M4.) This patch adds basic SoC enablement for the RISC-V cores: - basic dtsi, to be extended as additional drivers are added - SoC definition in soc/riscv32/openisa_rv32m1 for RI5CY / ZERO-RISCY - system timer driver for RI5CY, based on LPTMR0 peripheral The timer driver will be generalized a bit soon once proper multi-level interrupt support is available. Emphasis is on supporting the RI5CY core as the more capable of the two; the ZERO-RISCY SoC definitions are a good starting point, but additional work setting up a dtsi and initial drivers is needed to support that core.
