drm/amd/pm: force send pcie parmater on navi1x 

v1:
the PMFW didn't initialize the PCIe DPM parameters
and requires the KMD to actively provide these parameters.

v2:
clean & remove unused code logic (lijo)

Fixes: 1a18607c ("drm/amd/pm: override pcie dpm parameters only if it is necessary")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4671
