drm/amd/display: wait for set pipe mcp command completion
[Why]
When the driver sends a pipe set command to the DMCU FW, it does not wait
for the command to complete. This can lead to unpredictable behavior if,
for example, the driver were to request a pipe disable to the FW via MCP,
then power down some hardware before the firmware has completed processing
the command.
[How]
Wait for the DMCU FW to finish processing set pipe commands
