[PATCH v5 04/12] x86/common.c: load ucode in 64 bit or show loading ucode info in 32 bit on AP

["Fenghua Yu" <fenghua.yu@intel.com>]

From: Fenghua Yu <fenghua.yu@intel.com>

In 64 bit, load ucode on AP in cpu_init().

In 32 bit, show ucode loading info on AP in cpu_init(). Microcode has been
loaded earlier before paging. Now it is safe to show the loading microcode
info on this AP.
