[PATCH v3 00/16] target/riscv: deprecate riscv_cpu_options[]

[Daniel Henrique Barboza]

Hi,

In v2, after Vladimir's feedback, the following major changes were made:

- add default values in riscv_cpu_init() instead of doing gimmicks with
  setters and .set_default_value callbacks. The cost of having defaults
  for non-boolean properties in the parent class is smaller than having
  to deal with duplicated 'if cfg.prop == 0' checks in all setters;

- all properties are now being registered in the 'general_user_opts'
  hash. We were registering only the properties that KVM checks,
  Vladimir pointed out that this isn't consistent, we're making it
  consistent now.

Other smaller changes were made in patches 1, 2, 3 and 7.

Vladimir, due to the amount of changes I didn't add your "Tested-by" in
the patches. You're welcome to give this another try and add a tested-by
again :)

Patches based on riscv-to-apply.next. 

Changes from v2:
- patch 1:
  - remove 'bext_ver' from cpu.h
- patch 2 and 3: switched places
- patch 3 (former 2):
  - added hash implementation from patch 8
  - added pmu_mask setter()
  - pmu-mask and pmu-num can't be changed for vendor CPUs
- patches 4, 5, 6:
  - properties are now being added in the hash
- patch 7:
  - fixed string check in prop_vext_spec_set()
  - vext_spec is now being added in the hash
- patches 8, 9, 11, 12:
  - default values added in riscv_cpu_init()
  - no longer checking for "value == 0" in setters
