[PATCH v3 0/6] target/riscv: RVA23 profile support

[Daniel Henrique Barboza <dbarboza@ventanamicro.com>]

Hi,

In this new version we're now implementing u-mode and s-mode profile
dependencies, as suggested by Drew in v2. This makes implementing s-mode
profiles easier since those profiles usually inherits from both their
equivalent u-mode profiles and from a previous s-mode profile.

This is done in patch 3. Patch 4 is a change made to prevent a warning
that will occur after patch 6, where we're adding RVA23S64 by making it
dependent on both RVA23U64 and RVA22S64.

Patches based on alistair/riscv-to-apply.next.

Changes from v2:
- patch 3 (new):
  - add u_parent and s_parent attributes in RISCVCPUProfile
- patch 4 (new):
  - do not issue warnings when a profile runs in a newer priv_ver 
- patch 6 (former 4):
  - add RVA22S64 as the s_parent of RVA23S64. Declare RVA23S64 by listing
    just its own exclusive extensions
