drm/i915: Split sink_crc function in start, stop and read.
This is just a preparation patch to make clear what operation we
are performing. There is no functional change on the sink crc
logic.
hsw_disable_ips has been moved a bit further in the start function
to avoid disabling ips when sink crc is not going to be started.
and to avoid goto on this function.
v2: explain why hsw_disable_ips() call place has changed.
