ilk_compute_pipe_wm() assumes as zeroed pipe_wm structure when it

when the pipe_wm structure got embedded in the crtc state.

To fix it without too much fuzz, we need to resort to a memset().

MI_BATCH_BUFFER is nasty since it requires that userspace pass in the
correct batch length.

Let's switch to using MI_BATCH_BUFFER_START instead (like we do on
other platforms). Then we don't have to specify the batch length
at all, and the CS will instead execute until it sees the
MI_BATCH_BUFFER_END.

We still need the batch length since we do the CS TLB workaround
and copy the batch into the permanently pinned scratch object
and execute it from there. But for this we can simply use the
batch object length when the user hasn't specified the actual
batch length. So specifying the batch length becomes just a
way to optimize the batch copy a little bit.

We lost batch_len from a bunch of igts (including the quiesce batch)
so without this igt is utterly broken on 830/845. Also some igts such
as gem_cpu_reloc never specified the batch_len and so didn't work.
With MI_BATCH_BUFFER_START we don't have to fix up igt every time
someone forgets that 830/845 exist.

We use the vblank timestamps to generate the vblank frame counter value
on gen2. That means we need the pipe scanout position to be accurate
when we call drm_crtc_vblank_on(), otherwise the frame counter
guesstimate may jump when the pipe actually start.

What I observed on my 85x is that the DSL initially reads 0, and when
the pipe actually starts DSL jumps to vblank_start. On gen2 DSL==0 means
actually vtotal-1 (see update_scanline_offset()), so if we initially
get vtotal-1, and then very quickly vblank_start (or thereabouts), the
scanout position will appear to jump backwards by approximately one
vblank length. Which means the frame counter guesstimate will also
jump backwards. That's no good, so let's make sure the pipe has
started before we call drm_crtc_vblank_on().

primary DP encoder or the fake MST encoder), and it gets the DDI port
via intel_ddi_get_encoder_port() (which knows how to do the
