4.8-stable review patch. If anyone has any objections, please let me know.

From: John Hsu <KCHSU0@nuvoton.com>
commit a8961cae29c38e225120c40c3340dbde2f552e60 upstream.
In the FLL parameter calculation, the FVCO should choose the maximum one. The patch is to fix the bug about the wrong FVCO chosen.
