Add a media entity function to describe ISPs. ISPs overlap with existing
functions such as MEDIA_ENT_F_PROC_VIDEO_SCALER (when they include a
scaler). The new function should be used when the whole ISP is exposed
as a single entity, or for the central "catch all" entity of an ISP that
exposes additional entities for the scaler or other specific processing
blocks.
