In some scenarios with high timing requirements, frequent calls to
dma_alloc_coherent may trigger memory reclamation with low probability,
thereby increasing the overall time consumption per frame.

Through analysis of the code logic, we found that the flag
&vop->is_iommu_needed is redundant. After removing it, the iommu
will be enabled at the same time as the first atomic flush operation,
which may refresh the frame or not.
This modification can make codes more concise and allow iommu to be
initialized at an earlier time point, which may avoid the potential
problems(see commit 97e3aa256f ("drm/rockchip: vop2: Remove the
flag &vop2->is_iommu_needed"))

With CMDQ enabled, issuing a DCMD as the last command before disabling
CMDQ causes the eMMC controller to auto-gate its internal clock. The
state machine mismatch after exiting CMDQ mode triggers data-timeout
errors on all subsequent reads and writes, so the auto-clock-gate
function must be disabled whenever CMDQ is enabled.

If a new wb commit is too close to the timing of wb dma complete,
clearing the wb intr status will lose the wb dma complete status.
In this case, the software process is as follows:
vop_wb_commit() -> vop_wb_irqs_enable() -> Clear wb intr ->
vop_isr() -> vop_read_and_clear_wb_irqs()
Since we had cleared the intr in vop_wb_irqs_enable(), the value read
by vop_read_and_clear_wb_irqs() is 0, and we have lost the interrupt
status.

The drm_writeback_queue_job() function takes ownership of the passed
job and requires the caller to manually set the connector state
writeback_job pointer to NULL.
Therefore, there is no need to clear the writeback_job again.

For a specific case, there will be unexpected abnormal display:
If the logo display is disabled and the cubit lut is updated before
refreshing the first frame, the cubit lut function will be abnormal
along with display abnormalities.
The reason is:
The 3D look-up table is allocated via iommu while the flag
&vop2->is_iommu_needed, which to initialize the iommu, is first set
before refreshing the first frame. Therefore, for the above case,
the cubit lut function is working without iommu initialized.
Through analysis of the code logic, we found that the flag
&vop2->is_iommu_needed is redundant. After removing it, the iommu
will be enabled at the same time as the first atomic flush
operation, which may refresh the frame or not.
What's more, this method also help to avoid the cubit lut abnormal
issue in above case.
