drm/radeon/kms: fix DDIA enable on some rs690 systems

commit fdfc61594e6de21c23f955818ef78bcab9bafe40 upstream.

DVOOutputControl checks the value of of bios scratch reg 3
on some tables and assumes the encoder is already enabled
if the DFP2_ACTIVE bit is set.  Clear that bit so the table
sets the DDIA enable bit properly.
