From: Stephen Warren <swarren@xxxxxxxxxx>
Beaver's PCIe lane configuration most closely matches x2 x2 x2 rather
than x4 x1 x1, since clocks 0 and 2 are used, and lanes 0 and 5 are used,
and the only way those align is with a x2 x2 x2 configuration.
Also, disable root port 1; there's nothing connected to it. Root port 0
is the on-board PCIe Ethernet, and port 2 is the mini-PCIe slot.
