x86/fpu: Remove run-once init quirks
Remove various boot quirks that came from the old code. The new code is cleanly split up into per-system and per-cpu init sequences, and system init functions are only called once. Remove the run-once quirks. Cc: Andy Lutomirski <luto@amacapital.net> Cc: Borislav Petkov <bp@alien8.de> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: Fenghua Yu <fenghua.yu@intel.com> Cc: H.
