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.
