2a1fe39a5b drm/amd: Fix logic error in sienna_cichlid_update_pcie_parameters()
While aligning SMU11 with SMU13 implementation an assumption was made that
`dpm_context->dpm_tables.pcie_table` was populated in dpm table initialization
like in SMU13 but it isn't.

So restore some of the original logic and instead just check for
amdgpu_device_pcie_dynamic_switching_supported() to decide whether to hardcode
values; erring on the side of performance.

Since, it causes a regression in which eDP displays with PSR support,
but no Replay support (Sink support <= 0x03), fail to enable PSR and
consequently all IGT amd_psr tests fail. So, revert this until a more
suitable fix can be found.

the root port goes into D3cold which is incompatible with BACO.

This happens because in this case dGPU is connected to a bridge between
root port which causes BOCO detection logic to fail.  Fix the intent of
the logic by looking at root port, not the immediate upstream bridge for

a drm_connector as a common base.
