Attach the S2-only secure camera preview buffers with dummy drm
device during dma_buf_attach. This will ensure when sg_dma_address
will return the phys address for this buffer as its not backed
by a context-bank.

Attach the dmabuf with cp-pixel vmid to secure-cb device and the
tvm vmid in HLOS to DRM device to support CSF 2.5. Some cases like
DEMURA has dmabuf set with both cp-pixel & tvm VMIDs as its used
in HLOS and shared with Trusted-vm. Attach to secure-cb device in
these cases.

Both trusted-vm and secure-camera preview buffers uses the same
VMID_TVM. In primary-vm, the check is used to determine the camera
preview usecase and attach it to the correct device. This is not
necessary for trusted-vm as it can default to nested trusted-vm
context bank. Avoid the check while its in trusted-vm.

During the gem prime_fd_to_handle, attach the drm device to the
secure camera preview buffers. For CSF 2.5 solution, the DRM device
DT will have a special entry as indication to memory driver based on
which the buffer is handled differently. For older solution, the
attaching DRM device has no impact as the secure camera preview
buffer would be S2-only buffer.

Commit d1d1173 ("disp: msm: update msm_gem ops and remove unused
drm_driver callbacks") Update msm_gem and msm_drv to comply with
latest 5.15 kernel.Modify dma_buf_vmap() and dma-buf's vmap callback
to use truct dma_buf_map. Rename dma_resv_get_excl_rcu to _unlocked.
Remove deprecated GEM and PRIME callbacks.
This change adapts all the interface change for kernel version 5.10
and version 5.15..

Many upstream files and APIs have been removed in downstream
driver. Some function definintions are left dangling without
any caller. Remove the functions which are not used downstream.

Remove DMA_ATTR_IOMMU_USE_LLC_NWA and DMA_ATTR_IOMMU_USE_UPSTREAM_HINT
attributes as they are no longer needed since io-coherency is enabled.
Passing this attribute is a no op since buffer is io-coherent and will
be mapped with a write allocate policy contradicting intention
of that attribute.

dma_buf_get_flags is deprecated. Rather than using its updated API, avoid
checking flags and instead default to non secure context bank always.
Logic is already in place to detach from non secure and attach to secure
if needed based on plane property.
This change also removes the check for cached buffers since moving forward
all buffers will be cached so there is no need for this.

This change replaces kzfree with kfree as kzfree has been
renamed.
While moving to the latest 5.10 tip, additional small changes
were required to resolve compilation issues:
set_dma_ops has moved from dma-mapping to dma-map-ops header.
This change includes the new header file required.
drm_panel_add returns void, this change removes the expected
return value check.
drm_prime_pages_to_sg takes an additional parameter. This change
passes in the drm_device pointer the function is looking for.
Remove an unused variable in sde_crtc vblank function.

Assign default drm device for dma buf_attach when
IOMMMU is not present and for stage-2 only buffers.
Avoid setting lazy_unmap for stage-2 only buffers as
it doesn't have any impact without nested translations.
Assign default drm device when no device is found to
support transitions between secure usecases where
the nested context banks might not be attached back
at the prime_fd_to_handle time. These buffers would
be attached with the correct context bank device
during the delayed_import.

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.
