[PATCH 1/1] x86/tsr: Fix tsc frequency enumeration failure on lightning mountain SoC

[Dilip Kota]

Frequency descriptor of Lightning Mountain SoC doesn't have all the
frequency entries so resulting in the below failure causing kernel hang.

[    0.000000] Error MSR_FSB_FREQ index 15 is unknown
[    0.000000] tsc: Fast TSC calibration failed

So, add all the frequency entries in the Lightning Mountain SoC frequency
descriptor.

Fixes: 0cc5359d8fd45 ("x86/cpu: Update init data for new Airmont CPU model")
Fixes: 812c2d7506fd ("x86/tsc_msr: Use named struct initializers")
