riscv: mm: dma-noncoherent: nonstandard cache operations support
Introduce support for nonstandard noncoherent systems in the RISC-V architecture. It enables function pointer support to handle cache management in such systems. This patch adds a new configuration option called "RISCV_NONSTANDARD_CACHE_OPS." This option is a boolean flag that depends on "RISCV_DMA_NONCOHERENT" and enables the function pointer support for cache management in nonstandard noncoherent systems.
