arm: a37xx: pci: Do not try to access other buses when link is down If a PIO request is executed while link-down, the whole controller gets stuck in a non-functional state, and even after link comes up again, PIO requests won't work anymore, and a reset of the whole PCIe controller is needed. Therefore we need to prevent sending PIO requests while the link is down. Signed-off-by: Pali Rohár <pali@kernel.org> Reviewed-by: Stefan Roese <sr@denx.de>
