[RFC 5/6] omapdss: DPI: make dpi_get_channel take DPI reg-id

[Archit Taneja <archit@ti.com>]

To support multiple DPI instances, dpi_get_channel needs to take the DPI
instance's reg-id to get the corresponding channel. Make it take this
argument.

We just pass 0 in the non-DT path, since we don't support multiple instances
in the non-DT case.
