PCI: tegra194: Set EP alignment restriction for inbound ATU
Tegra194 and Tegra234 PCIe EP controllers have 64K alignment restriction
for the inbound ATU. Set the endpoint inbound ATU alignment to 64kB in the
Tegra194 PCIe driver.
Fixes: c57247f940e8 ("PCI: tegra: Add support for PCIe endpoint mode in Tegra194")
