drm/amd/display: change dcc_rate from 1 to 2 for log use only

Browse source

[why]
The dcc_rate value does not affect any watermark, TTU or DLG output; it
only affects the Z8 stutter-related logging. The hardware
DisplayModeSupported formula uses a dcc_rate of 4, while DML2 currently
uses 1.

[how]
Change dcc_rate from 1 to 2 so the logged value is closer to the
hardware formula.
