config, x86: Properly space pad the X86IntelMPBus Entry descriptions
According to the Intel Multi Processor Specification rev 1.4 (-006) (*), section 4.3.2 Bus Entries, Bus type strings are >>6-character ASCII (blank-filled) strings<<. This patch properly pads the entries with the missing spaces at the end. (*) http://www.intel.com/design/pentium/datashts/24201606.pdf Committed by Jason Lowe-Power <power.jg@gmail.com>
