[PATCH] ARM:Orion5x: Fix panic at boot for PCI IO reservation

[Andrew Lunn]

Orion5x, and all other orion based systems have a PCI(E) IO window
size of 1Mbyte. Recent changes to mach/io.h mean that by default the
kernel does not allow such large windows, it refuses to reserve that
much resource space, triggering a panic.

Reduce the PCI(E) IO window size to the normal 64K.
