soc/amd/sabrina/makefile: use Sabrina as SoC name in amdfwtool call

Now that the amdfwtool support for Sabrina is in place, change the
SoC name parameter passed to amdfwtool from Cezanne to Sabrina.

The fw.cfg file still points to the Cezanne binaries, but since
commit 9cb0a05dfb (soc/amd/sabrina: Add
prompt for AMDFW_CONFIG_FILE) this can be overridden via the Kconfig
config file in the build. As soon as the Sabrina PSP binaries are
available in 3rparty/amd_blobs, the fw.cfg file will be updated to use
the correct ones for Sabrina.
