x86/mce: Fix -Wmissing-prototypes warnings

Add the proper includes and make smca_get_name() static.

Fix an actual bug too which the warning triggered:

  arch/x86/kernel/cpu/mcheck/therm_throt.c:395:39: error: conflicting \
  types for ‘smp_thermal_interrupt’
   asmlinkage __visible void __irq_entry smp_thermal_interrupt(struct pt_regs *r)
                                         ^~~~~~~~~~~~~~~~~~~~~
  In file included from arch/x86/kernel/cpu/mcheck/therm_throt.c:29:
  ./arch/x86/include/asm/traps.h:107:17: note: previous declaration of \
	  ‘smp_thermal_interrupt’ was here
   asmlinkage void smp_thermal_interrupt(void);
