[Why & How]
Fix the typo for hubp_clear_tiling, currently calls hubp2_clear_tiling
for dcn401 instead of intended hubp401_clear_tiling.

[Why]
The double buffer cursor registers is updated by the cursor
vupdate event. There is a gap between vupdate and cursor data
fetch if cursor fetch data reletive to cursor position.
Cursor corruption will happen if we update the cursor surface
in this gap.
[How]
Modify the cursor request mode to the beginning prefetch always
and avoid wraparound calculation issues.

[WHY]
When the system powers up eDP with external monitors in seamless boot
sequence, stutter get enabled before TTU and HUBP registers being
programmed, which resulting in underflow.
[HOW]
Enable TTU in hubp_init.
Change the sequence that do not perpare_bandwidth and optimize_bandwidth
while having seamless boot streams.

[why]
Updating the cursor enablement register can be a slow operation and accumulates
when high polling rate cursors cause frequent updates asynchronously to the
cursor position.
[how]
Since the cursor enable bit is cached there is no need to update the
enablement register if there is no change to it. This removes the
read-modify-write from the cursor position programming path in HUBP and
DPP, leaving only the register writes.

[Why]
When HUBP is power gated, the SW state can get out of sync with the
hardware state causing cursor to not be programmed correctly.
[How]
Similar to DPP, add a HUBP reset function which is called wherever
HUBP is initialized or powergated. This function will clear the cursor
position and attribute cache allowing for proper programming when the
HUBP is brought back up.

[Why]
There are a few cleanup and refactoring tasks that need to be done
with the DML2.1 wrapper and DC interface to remove dependencies on
legacy structures and N-1 prototypes.
[How]
Implemented pipe_ctx->global_sync.
Implemented new functions to use pipe_ctx->hubp_regs and
pipe_ctx->global_sync:
- hubp_setup2
- hubp_setup_interdependent2
- Several other new functions for DCN 4.01 to support newer structures
Removed dml21_update_pipe_ctx_dchub_regs
Removed dml21_extract_legacy_watermark_set
Removed dml21_populate_pipe_ctx_dlg_param
Removed outdated dcn references in DML2.1 wrapper.

[WHY]
The `dc_tiling_info` union previously did not have a field to
specify the active GFX format, assuming only one format would
be used per DCN version. from DCN4+, support for switching
between different GFX formats is introduced, requiring a way
to track which format is currently in use.
[HOW]
Updated the `dc_tiling_info` union to include a new field that
explicitly indicates the currently used GFX format.
This allows the system to determine the active GFX format
and take the correct programming path accordingly.
[Description]
The union `dc_tiling_info` has been updated to support multiple
GFX formats by adding a new field for identifying the active format.
This update ensures that the correct programming path is followed
based on the selected format. All references to `dc_tiling_info`
in the codebase have been updated to reflect the new structure.

[WHAT & HOW]
Poniters, such as dc->clk_mgr, are null checked previously in the same
function, so Coverity warns "implies that "dc->clk_mgr" might be null".
As a result, these pointers need to be checked when used again.
This fixes 10 FORWARD_NULL issues reported by Coverity.

[WHAT & HOW]
According to register specifications, the CURSOR_DST_X_OFFSET
is relative to the start of the data viewport, not RECOUT space.
In this case we must transform the cursor coordinates passed to
hubp401_cursor_set_position into viewport space to program this
register. This fixes an underflow issue that occurs in scaled
mode with low refresh rate.
