This struct member is stored to in the function that calls the function
which uses it. That's possible with a function argument instead of
storing to a struct member. Pass the pixel_rate as an argument instead
to simplify the code. Note that dp_ctrl_link_maintenance() was storing
the pixel_rate but never using it so we just remove the assignment from
there.

dp_ctrl_on_link() almost doesn't even use the pixel_clk either. It just
prints the value. I kept it around because maybe it is useful? But if
not, then we can remove even more code.
