Jani Nikula 83d2bdb6a0 drm/i915: significantly reduce the use of <drm/i915_drm.h> 
The #include has been splattered all over the place, but there are
precious few places, all .c files, that actually need it.

v2: remove leftover double newlines

* Presumably, when dda3 is added in, it gets to adjust the dda2_inc value

* So,
* dda1_ideal = subcarrier/pixel * 4096
* dda1_inc = floor (dda1_ideal)
* dda2 = dda1_ideal - dda1_inc

* then pick a ratio for dda2 that gives the closest approximation. If
* you can't get close enough, you can play with dda3 as well. This
* seems likely to happen when dda2 is small as the jumps would be larger

* The pipe scanline counter behaviour looks as follows when

*
* time ->
*
* dsl=vtotal-1 | |
* || ||
* ___| | ___| |
* / | / |
* / | / |
* dsl=0 ___/ |_____/ |
* | | | | | |
* ^ ^ ^ ^ ^
* | | | | pipe vblank/first part of tv vblank
* | | | bottom margin
* | | active
* | top margin
* remainder of tv vblank
*
* When the TV encoder is used the pipe wants to run faster
* than expected rate. During the active portion the TV
* encoder stalls the pipe every few lines to keep it in
* check. When the TV encoder reaches the bottom margin the
* pipe simply stops. Once we reach the TV vblank the pipe is
* no longer stalled and it runs at the max rate (apparently
* oversample clock on gen3, cdclk on gen4). Once the pipe
* reaches the pipe vtotal the pipe stops for the remainder
* of the TV vblank/top margin. The pipe starts up again when
* the TV encoder exits the top margin.
*
* To avoid huge hassles for vblank timestamping we scale
* the pipe timings as if the pipe always runs at the average
* rate it maintains during the active period. This also
* gives us a reasonable guesstimate as to the pixel rate.
* Due to the variation in the actual pipe speed the scanline
* counter will give us slightly erroneous results during the
* TV vblank/margins. But since vtotal was selected such that
* it matches the average rate of the pipe during the active
* portion the error shouldn't cause any serious grief to
* vblank timestamps.
*
* For posterity here is the empirically derived formula
* that gives us the maximum length of the pipe vblank
* we can use without causing display corruption. Following
* this would allow us to have a ticking scanline counter
* everywhere except during the bottom margin (there the
* pipe always stops). Ie. this would eliminate the second
* flat portion of the above graph. However this would also
* complicate vblank timestamping as the pipe vtotal would
* no longer match the average rate the pipe runs at during
* the active portion. Hence following this formula seems
* more trouble that it's worth.
*
