riscv: cache: Implement i/dcache [status, enable, disable]
AndeStar RISC-V(V5) provide mcache_ctl register which can configure I/D cache as enabled or disabled. This CSR will be encapsulated by CONFIG_RISCV_NDS. If you want to configure cache on AndeStar V5 AE350 platform. YOu can enable [*] AndeStar V5 ISA support by make menuconfig. This approach also provide the expansion when the vender specific features are going to join in. Signed-off-by: Rick Chen <rick@andestech.com> Cc: Greentime Hu <greentime@andestech.com>
