Include <drm/*.h> instead of relative path from include/drm, then
remove the -Iinclude/drm compiler flag.
While we are here, use <...> instead of "..." for include/linux/*.h
and include/sound/*.h headers too.

BCM2835's PLLD_DSI1 divider doesn't give us many choices for our pixel
clocks, so to support panels on the Raspberry Pi we need to set a
higher pixel clock rate than requested and adjust the mode we program
to extend out the HFP so that the refresh rate matches.

I'm going to hook vc4 up to the sphinx build, so clean up its comments
to not generate warnings when we do.

If dsi_connector fails to allocate, the exit path via label 'fail'
checks if connector is null, which it always is, so the cleanup
that destroys connector is never going to be called. Hence the
failure path can be more optimally performed by removing this
and just returning ERR_PTR(-ENOMEM). This also removes the need
to initialize connector to NULL, and we can also remove ret too.

The DSI0 and DSI1 blocks on the 2835 are related hardware blocks.
Some registers move around, and the featureset is slightly different,
as DSI1 (the 4-lane DSI) is a later version of the hardware block.
This driver doesn't yet enable DSI0, since we don't have any hardware
to test against, but it does put a lot of the register definitions and
code in place.
