drm/amd/display: increased min_dcfclk_mhz and min_fclk_mhz
[why]
Originally, PMFW said min FCLK is 300Mhz, but min DCFCLK can be increased
to 400Mhz because min FCLK is now 600Mhz so FCLK >= 1.5 * DCFCLK hardware
requirement will still be satisfied. Increasing min DCFCLK addresses
underflow issues (underflow occurs when phantom pipe is turned on for some
Sub-Viewport configs).
[how]
Increasing DCFCLK by raising the min_dcfclk_mhz
