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.

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.

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.
