Andrew Murray dfbee31d50 PCI: rcar: Fix incorrect programming of OB windows
[ Upstream commit 2b9f217433e31d125fb697ca7974d3de3ecc3e92 ]

The outbound windows (PCIEPAUR(x), PCIEPALR(x)) describe a mapping between
a CPU address (which is determined by the window number 'x') and a
programmed PCI address - Thus allowing the controller to translate CPU
accesses into PCI accesses.

However the existing code incorrectly writes the CPU address - lets fix
this by writing the PCI address instead.

For memory transactions, existing DT users describe a 1:1 identity mapping
and thus this change should have no effect. However the same isn't true for
I/O.
