Implement ganged mode support for the Tegra DSI driver. The DSI host
controller to gang up with is specified via a phandle in the device tree
and the resolved DSI host controller used for the programming of the

If DISP1 is a PLLD/D2 child, it cannot go over 370MHz. The cause
of this is not quite clear. This can be overcomed by further
halving the PLLD/D2 if the target parent rate is over 800MHz.
This way DISP1 and DSI clocks will have the same frequency. The
shift divider in this case has to be calculated from the
original PLLD/D2 frequency and is passed from the DSI driver.

Only T30 is supported for now but T20 support can be added
if any supported devices will be found.
Driver is wrapped as panel driver since Tegra DC driver supports
only panel drivers calls.
