mb/google/poppy/variant/atlas: enable USB acpi
Main objective for this change is to export the bluetooth reset
gpio to the kernel for use in an rf-kill operation.
To do so, we enable USB acpi and define all of the USB2 devices,
which includes bluetooth's reset gpio information.
BUG=b:122540489
BRANCH=None
TEST=emerge-atlas coreboot chromeos-bootimage
$cat sys/firmware/acpi/tables/SSDT > /tmp/ssdt.dat &
retrieve ssdt.dat from DUT &
$iasl -d ./ssdt.dat & check the HS03 node is with "reset-gpio"
under _DSD object
