svn commit: r198431 - head/sys/dev/pci

[Marcel Moolenaar]

New Revision: 198431
URL: http://svn.freebsd.org/changeset/base/198431

Log:
  BIOSes, buggy or otherwise, are i386 or amd64 specific.
  Have the early USB takeover enabled for i386 and amd64
  by default.
  This also avoids a panic on PowerPC where the resource
  isn't released properly and we find a busy resource
  when the USB host controller wants to allocate it...
