Subject: [PATCH 4270/4736] drm/amd/display: Change Navi14's DWB flag to 1
[Why]
DWB (Display Writeback) flag needs to be enabled as 1, or system
will throw out a few warnings when creating dcn20 resource pool.
Also, Navi14's dwb setting needs to match Navi10's,
which has already been set to 1.
[How]
Change value of num_dwb from 0 to 1.
