intel/common/cpu: Add function to get microcode patch pointer
Add mp_current_microcode() function to get the microcode patch pointer.
Use this function to avoid reading the microcode patch from the boot
media. init_cpus() would initialize microcode_patch global variable to
point to microcode patch in boot media and this function can be used
to access the pointer.
