[PATCH] drm/amd/powerplay: bug fix for pcie parameters override

Bug fix for pcie paramerers override on swsmu.
Below is a scenario to have this problem.
pptable definition on pcie dpm:
0 -> pcie gen speed:1, pcie lanes: *16
1 -> pcie gen speed:4, pcie lanes: *16
Then if we have a system only have the capbility:
pcie gen speed: 3, pcie lanes: *8,
we will override dpm 1 to pcie gen speed 3, pcie lanes *8.
But the code skips the dpm 0 configuration.
So the real pcie dpm parameters are:
0 -> pcie gen speed:1, pcie lanes: *16
1 -> pcie gen speed:3, pcie lanes: *8
Then the wrong pcie lanes will be toggled.
