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

[ Upstream commit dc8a887de1a7d397ab4131f45676e89565417aa8 ]

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: 1a18607c07bb ("drm/amd/pm: override pcie dpm parameters only if it is necessary")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4671
