This change takes advantage of a HW feature that synchronize
flush operation on CTL1 to CTL0, to keep dual DSI pipes in
sync.

In MDP5, CTL contains information of the whole pipeline whose
output goes down to a display interface. In various cases, one
interface may require 2 CRTCs, but only one CTL. Some interfaces
also require to use certain CTLs.
Instead of allocating CTL for each active CRTC, this change is to
associate a CTL with each interface.

This change is to add properties alpha/zpos/blend_mode to mdp5 plane
for alpha blending operation to generate the blended output.

MDP FLUSH registers could indicate if the previous flush updates
has taken effect at vsync boundary. Making use of this H/W feature
can catch the vsync that happened between CRTC atomic_flush and
*_wait_for_vblanks, to avoid unnecessary wait.
This change allows kms CRTCs to use their own *_wait_for_commit_done
functions to wait for FLUSH register cleared at vsync, before commit
completion.

Some interfaces (WB, DSI Command Mode) need to be kicked off
through a START Signal. This signal needs to be sent at the right
time and requests in some cases to keep track of the pipeline
status (eg: whether pipeline registers are flushed AND output WB
buffers are ready, in case of WB interface).

DSI and WB interfaces need a more complex pipeline configuration
than the current mdp5_ctl_set_intf().
For example, memory output connections need to be selected for
WB. Interface mode (Video vs. Command modes) also need to be
configured for DSI.
This change takes care of configuring the whole pipeline as far
as operation mode goes. DSI and WB interfaces will be added
later.

mdp5_ctl_set_intf()'s second argument should be "int", not "enum mdp5_intf".
The passed in value is "intf", not "intf_id".

For example, use 'struct mdp5_smp *' everywhere instead of 'void *', but
only declare it as 'struct mdp5_smp;' in common headers, so the struct
body is still private. The accomplishes the desired modularity while
still letting the compiler provide some type checking for us.

MDP5 currently support one single CRTC with its private pipe.
This change allows the configuration of multiple CRTCs with
the possibility to attach several public planes to these CRTCs.
