soc/amd/stoneyridge: Update amdfw build

- The SMU firmware used to be named *.sbin, now is named *.csbin.
Update the makefile so that the files can be named as they are
delivered and don't have to be renamed.
- Add a Kconfig option to allow the secure os binaries to be excluded.

TEST=Build with old and new firmware, verify file sizes.
