mb/google/octopus: Disable BT before S5 entry
The CNVi wifi/bt module prevents entry into S5 by keeping internal SoC clocks running. Therefore it's necessary to disable BT prior to S5 entry. BUG=b:79606769 TEST= Test if BT device works under following cases: 1. Power-on 2. Press powerbtn before OS entry 3. Power-on from S5 again Change-Id: Ibc14b4080a27de48d197e16d0eed162603482de2 Signed-off-by: Hannah Williams <hannah.williams@intel.com> Reviewed-on: https://review.coreboot.org/26238 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
