Initial patch for Baikal-M arm64 based boards

[Slava Voronzoff]

Hello, I'm never send any patches, but I got arm64 board that is not
supported and plan to more or less add some support of it to openbsd
(because I like OpenBSD and want to run it here)

This is very simple patch that adds support of Pci-e on this board by
"matching" some OF_is_compatible to dwpcie.c file. Hope somebody can look
at it and add to cvs.
