None of the semantics of the function tell of it being a PRIME-exclusive
entry point. In fact, most drivers seem to be using it to translate a list
of pages into an sg table that can be used for GPU mapping later on, rather
than just for sharing an object's pages with another driver.

Move it across files and rename accordingly.

drm_prime_pages_to_sg() has no real dependency on PRIME/dma-buf interfaces.
It is a generic helper that converts a page array into a scatter/gather
table via dma_map_sg_attrs. Nothing in its implementation touches struct
dma_buf or import/export logic.
