platform/x86: ISST: Add support for MSR 0x54
To map Linux CPU numbering scheme to hardware CPU numbering scheme
MSR 0x53 is getting used. But for new generation of CPUs, this MSR
is not valid. Since this is model specific MSR, this is possible.
A new MSR 0x54 is defined for this purpose. User space can use the
API version to distinguish format from MSR 0x53.
Intel speed select utility is updated to use the new format based
on the API version.
