ACPI: LPSS: Fix the fractional clock divider flags 



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.

Fixes: 82f53f9e ("clk: fractional-divider: Introduce POWER_OF_TWO_PS flag")
