drm/amd/display: Refactor DPG test pattern logic for ODM cases
[Why]
Current DPG test pattern logic does not account for ODM configuration
changes after test pattern has already been programmed. For example, if
ODM2:1 is enabled after test pattern is already being output, the second
pipe is not programmed to output test pattern, causing half the screen
to be black.
[How]
Move DPG test pattern parameter calculations into separate function.
Whenever ODM pipe configuration changes, re-calculate DPG test pattern
parameters and program DPG if test pattern is currently enabled.
