Use DRM_DEV_INFO/ERROR/WARN instead of dev_info/err/debug to generate
drm-formatted specific log messages so that it will be easy to
differentiate in case of multiple instances of driver.

If there is only a single DSI interface, don't reserve the first two
layer-mixers for the dual-DSI use-case.
This was causing problems for WB, not being able to assign a LM, on
8x16, which has only two LM's and a single DSI.

For DSI cmd-mode and writeback, we need to write the CTL's START
register to kick things off, but we only want to do that once both
the encoder and the crtc have a chance to write their corresponding
flush bits. The difficulty is that when there is a full modeset
(ie. encoder state has changed) we want to defer the start until
encoder->enable(). But if only plane's have changed, we want to do
this from crtc->commit().
The start_mask was a previous attempt to handle this, but it didn't
really do the right thing since atomic conversion.
Instead track in the crtc state that the start should be deferred,
set to try from encoder's (or in future writeback's) atomic_check().
This way the state is part of the atomic state, and rollback can
work properly if an atomic test fails.

Since new display controller is called "dpu" instead of "mdp". Lets
make the name of the toplevel directory for the display controllers a
bit more generic.
