drivers/usb/acpi: Add AOLD Method for Intel Bluetooth
Add AOLD Method, which returns an integer based on
whether Audio Offload is enabled. Leave the existing
control of Audio Offload in `soc/soc_chip.h`. Add
`cnvi_bt_audio_offload` in the USB ACPI `chip.h` to
control the aforementioned return value.
The value in `soc/soc_chip.h` and `chip.h` should
match.
