feat: support ARCH_REMAP_KERNEL on libcpu/c906 (#9123) (#9171)

2024-07-11T03:46:26Z

feat: [libcpu/c906] support ARCH_REMAP_KERNEL This change was necessary to enable the remapping of the kernel image to a high virtual address region on the c906 platform. Changes: - Introduced new configuration options `ARCH_REMAP_KERNEL`, and `ARCH_USING_ASID` under the `ARCH_RISCV64` section. - Updated MMU initialization and switching functions to incorporate remapping handling. - Modified page table setup for proper memory attribute settings. - Added support for early memory setup, kernel remapping - Added conditional compilation for ASID support in the `rt_aspace` struct, since this is not enable currently for most architecture.
