gralloc: Back out hacks now that Mali-derping is fixed

Two reverts squashed, due to Mali-derping being fixed
in frameworks/native:

Revert "gralloc: avoid using framebuffer"

This reverts commit 5125ccc5b6d9a4bf1256a4a57f6d5f7d0ebe26c9.

Revert "gralloc:  Send first 2 FB buffers to carveout and next to UMP"

This reverts commit d288deb284f205c6b0eae04b27377c902afaf24e.
