Alistair Francis 47566421f0 target/riscv: pmp: Fixup TLB size calculation 
Since commit 4047368938 "accel/tcg: Introduce tlb_set_page_full" we
have been seeing this assert

    ../accel/tcg/cputlb.c:1294: tlb_set_page_with_attrs: Assertion `is_power_of_2(size)' failed.

When running Tock on the OpenTitan machine.

The issue is that pmp_get_tlb_size() would return a TLB size that wasn't
a power of 2. The size was also smaller then TARGET_PAGE_SIZE.

This patch ensures that any TLB size less then TARGET_PAGE_SIZE is
rounded down to 1 to ensure it's a valid size.
