Report more correct information for cache control

Browse Source 
On some platforms the number of bits in the cbm_mask might not be
divisible by 4 (and not even by 2), so we need to properly count the
bits.  Similar file, min_cbm_bits, is properly parsed and used, but if
the number is greater than one, we lose the information about
granularity when reporting the data in capabilities.  For that matter
always report granularity, but if it is not the same as the minimum,
add that information in there as well.
