Update the conditions for setting the SMU vcn reset caps in the SMU v13.0.6 initialization function. Specifically:

- Add support for VCN reset capability for firmware versions 0x00558200 and
  above when the program version is 0.
- Add support for VCN reset capability for firmware versions 0x05551800 and
  above when the program version is 5.
