riscv: enable HAVE_FAST_GUP if MMU 
Activate the fast gup for riscv mmu platforms. Here are some
GUP_FAST_BENCHMARK performance numbers:

Before the patch:
GUP_FAST_BENCHMARK: Time: get:53203 put:5085 us

After the patch:
GUP_FAST_BENCHMARK: Time: get:17711 put:5060 us

The get time is reduced by 66.7%! IOW, 3x get speed!
