soc/amd/stoneyridge: Name IO061 in ASL appropriately
AMD traditionally claims the resource at I/O port 61 for the onboard
PC-AT speaker. In later designs, the speaker may be omitted in favor
of routing the SPKR signal to the codec.
Some systems implement neither, and for those it is not correct to
identify the resource as a speaker. Modify the EISAID reported to
the OS depending on the system design. The default is that port 61
is reported as reserved. In order to report a speaker, add #define
in mainboard//dsdt.asl.
TEST=check /proc/ioports and iasl -d for both ways using a Grunt
BUG=b:117818432
