x86/tsr: Fix tsc frequency enumeration bug on Lightning Mountain SoC
[ Upstream commit 7d98585860d845e36ee612832a5ff021f201dbaf ]
Frequency descriptor of Lightning Mountain SoC doesn't have all the
frequency entries so resulting in the below failure causing a kernel hang:
Error MSR_FSB_FREQ index 15 is unknown
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")
