With CONFIG_DYNAMIC_DEBUG=y, the following compile error occurs:
drivers/gpu/drm/tegra/mipi-phy.c: In function ‘mipi_dphy_timing_validate’:

drivers/gpu/drm/tegra/mipi-phy.c:69:11: note: each undeclared identifier is reported only once for each function it appears in
Fix this by directly including the header that defines EINVAL.

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.
