[Why]
Code to enable DCN20 dynamic metadata feature is duplicated in two places
and was added to DCE110 enable stream.
[How]
Create DCN20 specific enable stream function for clarity, and add a hardware
sequencer function to program dynamic metadata to avoid the duplicate

Certain tests fail after a fresh reboot. This is caused by writing to

[How]
Make sure the stream is ungated before writing to its registers.
This also enables power-gating plane resources before init_hw
initializes them.
Additionally, this does some refactoring to move gating/ungating
from enable/disable_plane functions to where stream resources are
enabled/disabled.

[Why]
Logging hardware state can be done by triggering a write to the
debugfs file. It would also be useful to be able to read the hardware
state from the debugfs file to be able to generate a clean log without
timestamps.
[How]
Usage: cat /sys/kernel/debug/dri/0/amdgpu_dm_dtn_log
Threading is an obvious concern when dealing with multiple debugfs
operations and blocking on global state in dm or dc seems unfavorable.
Adding an extra parameter for the debugfs log context state is the
implementation done here. Existing code that made use of DTN_INFO
and its associated macros needed to be refactored to support this.
We don't know the size of the log in advance so it reallocates the
log string dynamically. Once the log has been generated it's copied
into the user supplied buffer for the debugfs. This allows for seeking
support but it's worth nothing that unlike triggering output via
dmesg the hardware state might change in-between reads if your buffer
size is too small.

Move cursor programming to inside the OTG_MASTER_UPDATE_LOCK
If graphics plane go from 1 pipe to hsplit, the cursor updates
after mpc programming and unlock. Which means there is a window
of time where cursor is enabled on the wrong pipe if it's on
the right side of the screen (i.e. case where cursor need to
move from pipe 0 to pipe 3 post split). This will cause pstate hang.
