mb/google/octopus: Add USB ACPI configuration for CNVi BT module 

This change enables exporting the reset GPIO for CNVi Bluetooth module to
the kernel for use in an rf-kill operation.

BUG=b:123296264
BRANCH=octopus
TEST=Boots to ChromeOS. Checked the SSDT table to ensure that the reset
gpio is exported under the device \_SB_.PCI0.XHCI.RHUB.HS09. Ensured
that the kernel btusb driver is able to find the exported GPIO in the
devices with CNVi BT module.
