omap_encoder_update() assigns an overlay manager to
dssdev->src->manager. This assignment is not needed, as the connections
in the display chain have already been made at connect step.

omapdrm supports atomic modesetting, and it seems to work ok. So let's
set the flag to enable the atomic modesetting API support.

Modified Tiler placement to utilize bitmaps for bookkeeping and
all placement algorithms. This resulted in a substantial savings
in time for all Tiler reservation and free operations. Typical
savings are in the range of 28% decrease in time taken with larger
buffers showing a 80%+ decrease.

The GEM object free handler frees memory allocated by the driver using
the pointer to the drm_gem_object instead of the pointer to the
omap_gem_object that embeds it. This doesn't cause any issue in practice
as the drm_gem_object is the first field of omap_gem_object, but would
cause memory corruption if the structure layout changes. Fix it.

The plane reset handler frees the plane state and allocates a new
default state, but when doing so attempt to free the plane state using
the base plane state pointer instead of casting it to the
driver-specific state object that has been allocated. Fix it by using
the omap_plane_atomic_destroy_state() function to destroy the plane
state instead of duplicating the code.

RK3036 registers layout is quite difference with rk3288 layout,
The IC design with different framework, rk3036 vop is VOP LITE,
and rk3288 is VOP FULL.
RK3036 support two overlay plane and one hwc plane, max output
resolution is 1080p. it support IOMMU, and its IOMMU same as
rk3288's.

Rk3288 vop timing registers is immediately register, when configure
timing on display active time, will cause tearing. use dclk reset is
not a good idea to avoid this tearing. we can avoid tearing by using
standby register.
Vop standby register will take effect at end of current frame, and
go back to work immediately when exit standby.
So we can use standby register to protect this context.
