x86 ucode: microcode logic update

Update microcode logic:
1. separate microcode_fini_cpu() into 2 level to avoid deadlock (when
fail at microcode_update_cpu);
2. cancel redundant collect_cpu_info at microcode.c level, use
relative function at microcode driver level;
3. separate microcode_resume_cpu from microcode_update_cpu, because
it's redundant (should only be called when S3 wakeup) and will block newer
microcode update when user update newer microcode.dat from user level
