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.

Fixes: 82f53f9ee5 ("clk: fractional-divider: Introduce POWER_OF_TWO_PS flag")
