For all the components that participate in DCN architecture, there is a header in the dc/inch/hw. For some reason, OPTC broke this pattern and added all the primary functions/structs associated with that in the dcn10_optc.h file. For consistency's sake, this commit introduces a new optc.h file and extracts the code from dcn10_optc to this new file.

* Output Pipe Timing Combiner (OPTC) includes two major functional blocks:

|
* Output Data Mapper (ODM) and Output Timing Generator (OTG).
|
|
*
|
|
* - ODM: It is Output Data Mapping block. It can combine input data from
|
|
* multiple OPP data pipes into one single data stream or split data from one
|
|
* OPP data pipe into multiple data streams or just bypass OPP data to DIO.
|
|
* - OTG: It is Output Timing Generator. It generates display timing signals to
|
|
* drive the display output.
