PCI: brcmstb: Fix potential premature regulator disabling
[ Upstream commit b7de1b60ecab2f7b6f05d8116e93228a0bbb8563 ]
The platform supports enabling and disabling regulators only on
ports below the Root Complex.
Thus, we need to verify this both when adding and removing the bus,
otherwise regulators may be disabled prematurely when a bus further
down the topology is removed.
Fixes: 9e6be018b263 ("PCI: brcmstb: Enable child bus device regulators from DT")
