We don't need to stash the encoder here. Instead we can simply pass it
around as an argument.

How does it work? From what I can tell from the information I find when
googling this part[1] and looking
Let's move these functions around to avoid having to forward declare
dp_ctrl_on_stream_phy_test_report(). Also remove
dp_ctrl_reinitialize_mainlink() forward declaration because we're doing
that sort of task.

This API isn't really more than a couple lines now that we don't store
the pixel_rate to the struct member. Inline it into the caller.

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
These patches do a little cleanup on the v9 patch[1] from Kuogee.
Changes from v1:
* Reduce code even more in second patch
* Pick up tags on first patch

drm/msm/dp: Reorganize code to avoid forward declaration
drm/msm/dp: Remove pixel_rate from struct dp_ctrl
