Subject[PATCH] x86/microcode: make stub function static inline
When building with C=1 W=1, both sparse and gcc complain:

CHECK arch/x86/kernel/cpu/microcode/core.c
./arch/x86/include/asm/microcode_amd.h:56:6: warning: symbol 'reload_ucode_amd' was not declared. Should it be static?
CC arch/x86/kernel/cpu/microcode/core.o
In file included from arch/x86/kernel/cpu/microcode/core.c:36:
./arch/x86/include/asm/microcode_amd.h:56:6: warning: no previous prototype for 'reload_ucode_amd' [-Wmissing-prototypes
56 | void reload_ucode_amd(void) {}
| ^~~~~~~~~~~~~~~~

And they're right - that function can be a static inline like its brethren.
