Ah! It looks like this is not a constant, but a common failure mode
among android-based devices!

In dmesg:

```
Warning: unable to open an initial console.
```

Simply removing the `console=` fixes the console.

See f295dc1 for a similar instance of
the issue.

The patches added here are required to build under some conditions, but
not all are ended up needed as CONFIG_DEBUG_FS is required to be active
otherwise the kernel doesn't even boot :/

The kernel size was reduced by:

 * Removing tracing support
 * Removing unneeded exfat and sdcardfs filesystems
 * Removing all sound support
 * Removing video input (camera) support

The latter options seem awfully shortsighted, until you remember that a goal is
to eventually deal with booting our own kernels through kexec.

The Moto Z Play device's boot partition size is putting us in a hard
spot.

Reduce size of kernel for motorola-addison + fixups
