Hi,

I'm sending this new version based on another observation I made during
another follow-up work (I'll post it shortly).

'mmu' and 'pmp' aren't really extensions in the most tradicional sense,
they're more like features. So, in patch 1, I moved both to the new
riscv_cpu_options array.

This was observed when I was trying to match each existing extension
with a priv_spec. I realized that we have 4 missing entries in
isa_edata_arr[] that we're considering as extensions: ext_zmmul, epmp,
mmu and pmp. The first 2 were sent as bug fixes for 8.1. mmu and pmp
were moved to riscv_cpu_options[] to be handled as such.

A small cosmetic change was made in patch 9 as well.

Patches missing review: 1, 3, 4, 8, 10, 11 

Changes from v4:
- patch 1:
  - add 'mmu' and 'pmp' in riscv_cpu_options
- patch 9:
  - changed 'max' cpu 'for' loop to use ARRAY_SIZE()
- v4 link: https://lore.kernel.org/qemu-riscv/20230718210329.200404-1-dbarboza@ventanamicro.com/
