Marco Felsch 5b3b0f7f73 clk: imx: pll14xx: align pdiv with reference manual 
commit 37cfd5e457cbdcd030f378127ff2d62776f641e7 upstream.

The PLL14xx hardware can be found on i.MX8M{M,N,P} SoCs and always come
with a 6-bit pre-divider. Neither the reference manuals nor the
datasheets of these SoCs do mention any restrictions. Furthermore the
current code doesn't respect the restrictions from the comment too.

Therefore drop the restriction and align the max pre-divider (pdiv)
value to 63 to get more accurate frequencies.
