[U-Boot] [PATCH] vexpress64: Juno: Change PCI buss addresses for IO to start from zero.

[Liviu Dudau]

Juno uses a 1:1 mapping between CPU and PCI addresses for IO. First,
that will trip devices that cannot use more than 16 bits of addresses
for IO, second it is un-necessary as the system can handle zero-based
PCI addresses just fine.

Change the mapping to start IO bus addresses from zero.
