clk: wm831x: Fix wm831x_clkout_get_parent
Current code looks strange because calling wm831x_clkout_set_parent() with 0 as
parent parameter, wm831x_clkout_get_parent() will return 1.
According to the datasheet:
R16528 (4090h) Clock Control1
BIT 0: CLKOUT output source select
0 = FLL output
1 = 32.768kHz oscillator
Thus fix the entry order in wm831x_clkout_parents[] to make it has
the same meaning as the datasheet and make the return value
of wm831x_clkout_get_parent() consistent with the parent pass to
wm831x_clkout_set_parent().
