soc/intel/common/block/cpu/cpulib: use mca_get_bank_count() 

Use the common mca_get_bank_count function instead of open-coding the
functionality to get the MCA bank number. Also re-type the num_banks
variable from signed in to unsigned int, since the number of MCA bank is
always positive, and make it constant.
