[PATCH v2 9/9] clk: meson: axg: add the fractional part of the fixed_pll

[Jerome Brunet]

The fixed_pll also has a fractional part. On axg s400 board, without
this parameter, the calculated rate is off by ~8Mhz (0,4%). The fixed_pll
being the root of the peripheral clock tree, this error is propagated to
the rest of the clocks

Adding the definition of the parameter fixes the problem
