Treat model == 0x4f as Broadwell
From Intel SDM Vol 3:
Table 35-29 lists MSRs that are common to processors based on the
Broadwell microarchitectures (including CPUID signatures 06_3DH,
06_47H, 06_4FH, and 06_56H).
* config/i386/driver-i386.c (host_detect_local_cpu): Treat
model == 0x4f as Broadwell.
