soc/amd: Change Morgana codename to Phoenix

Now that the next generation of APUs is officially announced, we can
unmask morgana.

The chip formerly known as Morgana is actually Phoenix.

Surprise!

This patch just changes the name across the entire codebase.

Note that the fw.cfg file will stay pointing to the
3rdparty/amd_blobs/morgana/psp directory until the amd_blobs_repo is
updated.
