PCI: starfive: Fix Runtime PM handling and teardown ordering
The starfive_pcie_remove() path incorrectly disabled runtime PM
before executing plda_pcie_host_deinit(), which can cause unmanaged
hardware register access in plda_pcie_host_deinit() while power domains or
clocks are disabled.
Fix this by restructuring starfive_pcie_remove() to deinitialize the host
controller first while runtime PM is active, followed by a synchronous
pm_runtime_put_sync() and pm_runtime_disable().
This bug was found in automated AI review by sashiko-bot.
