Ryan Harkin	bc8d3bc023	vexpress64: compile Juno PCIe conditionally ... Only compile in PCIe support if the board really uses it. Provide a __weak stub for the init function if e.g. FVP is being built.

Andre Przywara	0ee1a22b6d	Juno: don't print PCI debug information by default ... On a Juno r1 the PCI controller init routine outputs the rather boring ATR entry information. Do this only with DEBUG defined to avoid cluttering the user's terminal.

Liviu Dudau	2fdc9b741b	vexpress64: Juno: Add initialisation code for Juno R1 PCIe host bridge. ... Juno R1 has an XpressRICH3 PCIe host bridge that needs to be initialised in order for the Linux kernel to be able to enumerate the bus. Add support code here that enables the host bridge, trains the links and sets up the Address Translation Tables.
