x86/tsc_msr: Correct Silvermont reference clock values

Atom processors use a 19.2 MHz crystal oscillator.

Early processors generate 100 MHz via 19.2 MHz * 26 / 5 = 99.84 MHz.

Later preocessor generate 100 MHz via 19.2 MHz * 125 / 24 = 100 MHz.

Update the Silvermont-based tables accordingly,
matching the Software Developers Manual.

Also, correct a 166 MHz entry that should have been 116 MHz,
and add a missing 80 MHz entry.
