[PATCH 6/9] clk: tegra210: fix pllx dyn step calculation

[Rhyland Klein <rklein@nvidia.com>]

The logic for calculating the input rate used when figuring out
the proper dynamic steps for pllx was incorrect. It is supposed to
be calculated using parent_rate / m but it was just using the parent
rate directly, therefore using the wrong step values.
