When applying the PLL changes from the computed state object, make sure
to set the rate of the display controller module clock. Failing to do so
can yield to a situation where the parent will be set to the proper
pixel clock, but the module clock will be divided down to the rate that
is happened to be set to before the parent rate change.

Remove the tegra_dc_disable_window() function whose only purpose was to
allow tegra_plane_atomic_update() to also call it. Fix that by shuffling
tegra_plano_atomic_disable() to before tegra_plane_atomic_update().
While at it, also remove the overlay plane helper functions because they
are exactly the same as the primary plane helper functions.

The host1x driver prints out "disassembly" dumps of the command FIFO
and gather contents on submission timeouts. However, the output has
been quite difficult to read with unnecessary newlines and occasional
missing parentheses.
Fix these problems by using pr_cont to remove unnecessary newlines
and by fixing other small issues.

The gather filter is a feature present on Tegra124 and newer where the

Since Tegra186 the Host1x hardware allows syncpoints to be assigned to
specific channels, preventing any other channels from incrementing
them.
Enable this feature where available and assign syncpoints to channels
when submitting a job. Syncpoints are currently never unassigned from
channels since that would require extra work and is unnecessary with
the current channel allocation model.

Rather than request syncpoints for a struct device *, request them for a
struct host1x_client *. This is important because subsequent patches are
going to break the assumption that host1x will always be the parent for
devices requesting a syncpoint. It's also a more natural choice because
host1x clients are really the only ones that will know how to deal with
syncpoints.
Note that host1x clients are always guaranteed to be children of host1x,
regardless of their location in the device tree.

VC4's DSI1 has a bug where the AXI connection is broken for 32-bit
writes from the CPU, so we use the DMA engine to DMA 32-bit values
into registers instead. That sleeps, so we can't do it from the top
half.
As a solution, use an interrupt thread so that all our writes happen
when sleeping is is allowed.
v2: Use IRQF_ONESHOT (suggested by Boris)
v3: Style nitpicks.

The fence at the end of the frame will indicate the completion status.
If the frame completed normally, the fence is written to the address
given in the EVENT_WRITE_EOP packet. If preemption occurred in the
previous IB the address is adjusted by 2 DWs. If work submitted in the
frame was reset before completion, the fence address is adjusted by
four DWs. In the case that preemption occurred, and before preemption
completed a reset was initiated, the address will be adjusted with six
