Subject: riscv/Kconfig: make direct map manipulation options depend on MMU

ARCH_HAS_SET_DIRECT_MAP and ARCH_HAS_SET_MEMORY configuration options have
no meaning when CONFIG_MMU is disabled and there is no point to enable
them for the nommu case.

Add an explicit dependency on MMU for these options.
