[PATCH v2 12/23] OMAPDSS: DSI: Pass omap_dss_output within the driver

[Archit Taneja <archit@ti.com>]

When a panel driver calls a DSI function, it passes the omap_dss_device
pointer, this pointer currently propagates within the DSI driver to configure
the interface.

Extract the omap_dss_output pointer from omap_dss_device received from the panel
driver, pass the output pointer to DSI functions local to the driver to
configure the interface, these functions no longer need omap_dss_device since
the driver now maintains a copy of output parameters.

Replace dssdev->manager references with out->manager references as only these
will be valid later.

With the addition of outputs. There is a possibility that an omap_dss_device
isn't connected to an output, or a manager isn't connected to an output yet.
Ensure that the DSI interface functions proceed only if the output is non NULL.
