PCI: imx6: Fix i.MX8MP PCIe EP's occasional failure to trigger MSI
Correct occasional MSI triggering failures in i.MX8MP PCIe EP by applying
the correct hardware outbound alignment requirement.
The i.MX platform has a restriction about outbound address translation. The
pci-epc-mem uses page_size to manage it. Set the correct page_size for i.MX
platform to meet the hardware requirement, which is the same as inbound
address alignment.
Thus, align it with epc_features::align.
