feat: libcpu/risc-v: unify interrupt & IO on rv64

2024-09-11T22:06:51Z

This patch aims to unify the two currently separated RISC-V 64-bit architecture ports, 'virt64' and 'c906', into a single generic 'common64' port. The changes include renaming files and updating includes to use a unified 'interrupt.h' header, as well as making adjustments to IO and trap handling to be more consistent between the two architectures. Changes: - Renamed 'rt_interrupt.h' to 'interrupt.h' and updated includes accordingly. - Unified IO register access functions in 'riscv_io.h'. - Added 'opcode.h' for portable assembly support. - Updated 'plic.c' and 'plic.h' to handle interrupts in a unified manner. - Modified 'trap.c' to handle exceptions and interrupts consistently for 'rv64'.
