x86/tsr: Fix tsc frequency enumeration bug on Lightning Mountain SoC

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: 812c2d7506fd ("x86/tsc_msr: Use named struct initializers")
