From: Alvin Lee <[email protected]> - DC mode clock switch interface was previously only executed for DCN303. Enable it for DCN32x so that the interface is called correctly - Assign function pointers for DCN32x that are used in the dc mode interface - Update the dc mode interface to work generically for each ASIC - In update_clocks, make sure to consider softmax if we're in DC mode
