9d7c72743d disp: msm: remap dmabuf attach during secure transitions
During secure cb detach, gem objects stored in the aspace
active list are not cleaned up properly leading to crash
when secure cb attaches again. This change remaps dma
buffer for those gem objects.

a9574eb8c2 disp: msm: perform delayed buf attach during secure transitions
While transitioning from secure usecases, the secure
context bank is attached back only during the commit
phase. This leads to invalid secure context-bank device
issue, when the prime_to_fd call is made for the next
frame. Avoid it, by attaching to default drm device
during the prime_to_fd call and reattach it to the
secure context-bank device at the delayed import time.

The dma buffer associated with the gem object is already
unmapped during put_iova. Avoid unmapping it again in
put_pages.
