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.
