x86/fpu: Harmonize the names of the fpstate_init() helper functions
Harmonize the inconsistent naming of these related functions: fpstate_init() finit_soft_fpu() => fpstate_init_fsoft() fx_finit() => fpstate_init_fxstate() fx_finit() => fpstate_init_fstate() # split out 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.
