From: Wayne Lin <Wayne.Lin@xxxxxxx>
[Why]
Have the need to specify the CRC window on specific CRC engine.
dc_stream_configure_crc() today calculates CRC on crc engine 0 only and always
resets CRC engine at first.
[How]
Add index parameter to dc_stream_configure_crc() for selecting the desired crc
engine. Additionally, add another parameter to specify whether to skip the
default reset of crc engine.
