[PATCH v4 54/71] peci: cpu: Switch to new Intel CPU model defines

[Tony Luck]

New CPU #defines encode vendor and family as well as model.

N.B. Copy some macros from x86 <asm/cpu_device_id.h> and the
X86_VENDOR_INTEL define from <asm/processor.h> because this
code can be built for BMC's that are not based on x86 so
accessing those header files is problematic.
