Subject: treewide: Rename Sabrina to Mendocino

'Mendocino' was an embargoed name and could previously not be used
in references to Skyrim.  coreboot has references to sabrina both
in directory structure and in files. This will make life difficult
for people looking for Mendocino support in the long term. The code
name should be replaced with "mendocino".
