target/riscv/tcg: set 'mmu' with 'satp' in cpu_set_profile()

Recent changes in options handling removed the 'mmu' default the bare
CPUs had, meaning that we must enable 'mmu' by hand when using the
rva22s64 profile CPU.

Given that this profile is setting a satp mode, it already implies that
we need a 'mmu'. Enable the 'mmu' in this case.
