unmaintained/shift-axolotl-downstream: new device (MR 3637)

Downstream for kernel development, not for actual use.

Kernel defconfig taken from stock with:
- CONFIG_ANDROID_PARANOID_NETWORK unset
- CONFIG_DEVTMPFS set
- CONFIG_EXT4_FS_POSIX_ACL set
- CONFIG_LOCALVERSION set to "-downstream"
- CONFIG_SYSVIPC set
- CONFIG_USB_CONFIGFS_RNDIS set
- CONFIG_USER_NS set
