Tested on XO-1.5 using a build of Q3A62 plus this patch, against 10.1.3
and 11.2.0 os11, the following /ofw entries were visible:

/ofw/pci/isa at 11/rtc at i70/compatible -> 'olpc,xo1-rtc' 'pnpPNP,b00'
(previously only 'pnpPNP,b00')

/ofw/pci/display at 1/dcon/compatible -> 'olpc,xo1-dcon'
(previously not present)

/ofw/battery at 0/compatible -> 'olpc,xo1-battery'
(previously not present)
