CMOS battery gets reset upon force restart #1

This is actually caused by a bug in the HP BIOS, and can be fixed by "updating" the BIOS. (For an explanation, it rollbacks to 1.46). Out of the scope of this project.

EDIT: as it turns out, it ISN'T a bug in the BIOS, in fact it's actually just macOS writing to parts of the CMOS that it just doesn't like very much.

Update: as it turns out, RTCMemoryFixup is meant to be used in conjunction with rtc-blacklist... this has actually been fixed on my EFI but it hasn't been updated here. It's about time I updated this, anyways.

This is still broken in El C(r)apitan, and some more older versions of OS X. It's just a minor issue though, and if anyone wants to actually fix this once and for all, please do.
