Thierry Reding 72d3028615 drm/tegra: Relocate some output-specific code 
Some of the code in the CRTC's mode setting code is specific to the RGB
output or needs to be called slightly differently depending on the type
of output. Push that code down into the output drivers.

Wei Yongjun 85316eae48 drm/tegra: Fix return value check 
In case of error, the devm_ioremap_resource() function returns ERR_PTR()
and never NULL. The NULL test in the return value check should therefore
be replaced with IS_ERR().

Thierry Reding dec727399a drm/tegra: Add DSI support 
This commit adds support for both DSI outputs found on Tegra. Only very
minimal functionality is implemented, so advanced features like ganged
mode won't work.

Due to the lack of other test hardware, some sections of the driver are
hardcoded to work with Dalmore.
