Fix/align with the spec the DDI function and DP2 config programming
during enabling/disabling MST slave transcoders. On PTL the first patch
fixes a slave transcoder getting stuck issue. On PTL the DP2
configuration and on other ADLP+ platforms both the DDI function and the
DP2 configuration changes only align the code with the specification,
without actual problems reported that these woud fix.
