During gem fault, if aspace value is found to be NULL
pages map request will be failed. This change assigns
nonsecure aspace to gem object before mapping the pages
in such cases.

Add changes to re-apply the dma_map attributes during secure UI
to secure-video transition to avoid mismatch of attributes
between the import_attach newly created and the msm_iommu
mappings already existed.

Allocate DSI/LUTDMA buffers from VRAM when IOMMU is not
available. Add checks in msm_gem to avoid few operations
when aspace is not available due to no IOMMU. Parse the
VRAM size from device tree, when available.

Add plane buffer flag to get the correct aspace during
TUI VM usecase. FB_NON_SEC_DIR_TRANS plane flag is set
by user-mode to indicate S2-only non-secure buffer in
TUI VM. Return the default drm device when SMMU is not
available during get_aspace_device to make the working
seamless with/without SMMU.

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.

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.
