PCI: aardvark: Add 100 ms delay after link training
The Aardvark PCIe controller driver waits for the link to come up but
does not implement the mandatory 100 ms delay after link training
completes for speeds greater than 5.0 GT/s (PCIe r6.0 sec 6.6.1).
The driver already maintains a 'link_gen' field that holds the negotiated
link speed. Use it together with pci_host_common_link_train_delay() to
insert the required delay immediately after confirming that the link
is up.
