Legacy (non-atomic) page flip support is added to the driver by using the
mode_set_base CRTC function, that allows configuring a new framebuffer for
display. Since the function requires the primary plane's fb to be set
already, this is done prior to calling the function in the page flip helper
and reverted if the flip fails.
The vblank interrupt handler is also refactored to support passing an event.
The PIPE_TE_STATUS bit is also considered to indicate vblank on medfield
only, as explained in psb_enable_vblank.
It was tested by running weston on both poulsbo and cedartrail.

<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has
now been split into separate files for each object type, but still
includes most other KMS headers to avoid breaking driver compilation.
As a step towards fixing that problem, remove the inclusion of
<drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where
appropriate. Also remove the forward declarations of the drm_encoder and
drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not
needed in the header.
<drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a
forward declaration of struct drm_encoder in order to allow including it
as the first header in a compilation unit.

This takes care of the remaining chips using the old generic code.
We don't check if the pipe number is valid but the old code peeked in
the register map before checking anyways so just ignore it.

This patch aims to unify the bits and pieces that are common (or similar
enough) for pll clock calculations. Nothing makes use of this code yet
That will come in later patches.

Based on the spec, the CRT output doesn't use the lane. And the HDMI B output
uses the Lane0/1 while the HDMI C output uses the Lane 2/3. But currently
it will program all the four lanes for the CRT/HDMI.

Poulsbo needs a physical address in the cursor base register. We allocate a
stolen memory buffer and copy the cursor image provided by userspace into it.
When/If we get our own userspace driver we can map this stolen memory directly.
The patch also adds a mark in chip ops so we can identify devices that has this
requirement.

This provides the specific code for Poulsbo, some of which is also used for
the later chipsets. We support the GTT, the 2D engine (for console), and
the display setup/management. We do not support 3D or the video overlays.
In theory enough public info is available to do the video overlay work
but that represents a large task.
Framebuffer X will run nicely with this but do *NOT* use the VESA X
server at the same time as KMS. With a Dell mini 10 things like Xfce4 are
nice and usable even when compositing as the CPU has a good path to the
memory.
