disp: msm: use FB_NON_SEC_DIR_TRANS plane hint for TUI VM buffers

Selaa lähdekoodia 
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.
