The starfive_pcie_remove() path incorrectly disabled runtime PM
before executing plda_pcie_host_deinit(),
which can cause unmanaged hardware register access
while power domains or clocks are disabled.

Fix this by restructuring starfive_pcie_remove() to deinitialize
the host hardware first while runtime PM is active,
followed by a synchronous pm_runtime_put_sync() and pm_runtime_disable().
