x86/cpu: Print family/model/stepping in hex

924e101a7ab6 ("x86/debug: Dump family, model, stepping of the
boot CPU") had its good intentions to dump the exact F/M/S as an
aid during debugging sessions but its output can be ambiguous.
Fix that:

-smpboot: CPU0: Intel Core Processor (Broadwell) (fam: 06, model: 47, stepping: 02)
+smpboot: CPU0: Intel Core Processor (Broadwell) (family: 0x6, model: 0x47, stepping: 0x2)

Also, spell out "family".
