mb/google/skyrim: Enable SPL fusing on whiterun/winterhold

Enable whiterun/winterhold platforms to send the fuse SPL (security
patch level) command to the PSP.

BUG=b:254568112
TEST=On a platform that supports SPL fusing, a message indicating
that fusing was requested will appear in the coreboot console log,
followed by a puff of smoke when the fuse is set and the message
"OK" again on the debug console.  (Kidding about the smoke.)
