ACPI: LPSS: Fix the fractional clock divider flags
[ Upstream commit 3ebccf1d1ca74bbb78e6f8c38d1d172e468d91f8 ] The conversion to CLK_FRAC_DIVIDER_POWER_OF_TWO_PS uses wrong flags in the parameters and hence miscalculates the values in the clock divider. Fix this by applying the flag to the proper parameter.
