[PATCH BlueZ v2 11/15] android/hog: Add support for Scan Parameter Service

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

If primary is not provided meaning primary should be auto discovered it
probably means other primary services such as Scan Parameter Profile
are not being handled either so just handle ScPP as well in such case.
