Subject: [PATCH 4.4 41/51] PCI: altera: Reorder read/write functions

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bjorn Helgaas <bhelgaas@...gle.com>

commit f8be11ae3d2c9a1338da37ff91ff4c65922d21be upstream.

Move cra_writel(), cra_readl(), and altera_pcie_link_is_up() so a future
patch can use them in altera_pcie_retrain().  No functional change
intended.
