This patch fixes mbus configuration between Mixer, SDO and HDMI. The SDO
accepts only YUV444 on input. The HDMI in DVI mode accepts only RGB888. Now
Mixer is choosing proper output format depending on mbus format.

Current version of the driver does not support HDMI features
not present in DVI standard. Therefore DVI mode is used to
keep compatibility with DVI devices.

This patch changes the order of operations during stream on call. Now the
buffers are first queued to the driver and then the start_streaming method
is called.
This resolves the most common case when the driver needs to know buffer
addresses to enable dma engine and start streaming. Additional parameter
to start_streaming method have been added to simplify drivers code. The
driver are now obliged to check if the number of queued buffers is high
enough to enable hardware streaming. If not - it can return an error. In
such case all the buffers that have been pre-queued are invalidated.
This patch also updates all videobuf2 clients to work properly with the
changed order of operations.

Use the correct 'dma_addr' name for the buffer address. 'paddr' suggested
that this is the physical address in system memory. For most ARM platforms
these two are the same, but this is not a generic rule. 'dma_addr' will
also point better to dma-mapping api.

Plane sizes array was declared as unsigned long[], while unsigned int is
more than enough for storing size of the video buffer. This patch reduces
the size of the array by definiting it as unsigned int[].
