drm/prime: split array import functions v4
Mapping the imported pages of a DMA-buf into an userspace process
doesn't work as expected.
But we have reoccurring requests on this approach, so split the
functions for this and document that dma_buf_mmap() needs to be used
instead.
v2: split it into two functions
v3: rebased on latest changes
v4: update commit message a bit
