soc/amd/stoneyridge: Add selectable APU names

Add APU names of STONEYRIDGE and MERLINFALCON to Kconfig.  The existing
convention of SOC_AMD_PRODUCTNAME_PKG will be phased out.

Don't explicitely use the APU_STONEYRIDGE name yet when creating
default paths.  Prairie Falcon relies on the default setting, and this
will be addressed in a later change.
