soc/amd: Implement common reset API

Add an `amdblocks` internal API and rename
  soft_reset() => warm_reset()
  hard_reset() => cold_reset()
as these terms are commonly used in the surrounding code.

On Stoney Ridge, make board_reset() call cold_reset() to keep
current behaviour of common code calling hard_reset(). But add
a TODO if this is intended.

Note: Stoney Ridge is using CF9 for the actual reset but the
configuration for a cold reset doesn't use the usual full reset
bit but some other mechanism.
