riscv: select ARCH_HAS_STRICT_KERNEL_RWX only if MMU
ARCH_HAS_STRICT_KERNEL_RWX is not useful for NO-MMU systems.
Furthermore, has this option leads to very large boot image files on
64bits architectures, do not enable this option to allow supporting
no-mmu platforms such as the Kendryte K210 SoC based boards.
