riscv: mm: support Svnapot in huge vmap
As HAVE_ARCH_HUGE_VMAP and HAVE_ARCH_HUGE_VMALLOC is supported, we can
implement arch_vmap_pte_range_map_size and arch_vmap_pte_supported_shift
for Svnapot to support huge vmap about napot size.
It can be tested by huge vmap used in pci driver. Huge vmalloc with svnapot
can be tested by test_vmalloc with [1] applied, and probe this
module to run fix_size_alloc_test with use_huge true.
