Bug description:
  [Impact]

  Some cloud-focused kernels have CONFIG_BT enabled but cloud instances
  shouldn't need bluetooth support. Disabling the bluetooth subsystem
  reduces the amount of security-sensitive code we have to worry about
  in the cloud kernels and also has the nice side effect of minimizing
  build times and kernel sizes.

  The cloud kernels known to have bluetooth enabled include:

  * [B/D/E] linux-aws (arm64 only)
  * [X/B/D/E] linux-gcp
  * [B] linux-gke-4.15
  * [B] linux-gke-5.0
  * [X/B/D/E] linux-oracle

  [Test Case]

  1. Install patched kernel and reboot into it
  2. Ensure that the following command does NOT display any output:
     $ grep CONFIG_BT=[my] /boot/config-$(uname -r)

  [Regression Potential]

  There could be an unexpected dependence on bluetooth within one of the
  clouds but I think it is highly unlikely.
