Introduce a new live source flag for framebuffers. When a framebuffer is
created with that flag set, a live source is associated with the
framebuffer instead of buffer objects. The framebuffer can then be used
with a plane to connect it with the live source.

The R8A7790 DU can source frames directly from the VSP1 devices VSPD0
and VSPD1. VSPD0 feeds DU0/1 plane 0, and VSPD1 feeds either DU2 plane 0
or DU0/1 plane 1.
Allocate the correct fixed plane when sourcing frames from VSPD0 or
VSPD1, and allocate planes in reverse index order otherwise to
Register live sources for VSPD0 and VSPD1 and configure the plane source
at plane setup time to source frames from memory or from the VSP1.

Hello,
Here's a proposal for a different approach to live source in DRM based on an
idea by Daniel Vetter. The previous version can be found at
http://lists.freedesktop.org/archives/dri-devel/2015-March/079319.html.
The need comes from the Renesas R-Car SoCs in which a video processing engine
Live sources represent a hardware connection between a video stream
source and a CRTC, going through a plane. The kernel API lets driver
register live sources, and the userspace API lets applications enumerate
them.

Plane sources are configured by the VSPS bit in the PnDDCR4 register.
Although the datasheet states that the bit is updated during vertical
blanking, it seems that updates only occur when the DU group is held in
reset through the DSYSR.DRES bit. Restart the group if the source
changes.
The vsp1_entity_is_streaming() function is called in atomic context when
queuing buffers, and sleeps due to a mutex. As the mutex just protects
access to one structure field, fix this by replace the mutex with a
spinlock.
