drm/amd/display: Remove redundant if conditions
[WHY]
Coverity analysis flagged the two if conditions in
dcn30_dpp.c and dcn401_dpp.c as DEADCODE since they
are never true, since the variable
'program_prealpha_dealpha' is initialized at 0 and
never chagnes.
[HOW]
Removed the variable 'program_prealpha_dealpha' and
the if conditions.
