mb/google/poppy/variant/rammus: 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:119899987
TEST=build and flash to rammus, log into rammus and
'cat /sys/firmware/acpi/tables/SSDT > /tmp/ssdt.dml', copy
that ssdt.dsml to /tmp/ssdt.dml on host machine,
'iasl -d /tmp/ssdt.dml', then verify that "reset gpio"
shows up in the HS03 node's _DSD package in the table.
