manifest: allow syncing devices by their carrier-specific codenames

Currently, devices which are part of a larger family (i.e. jf or d2) are
grouped under their family's codename for syncing. If an uneducated user
is looking to build for the first time, this may lead to annoyances as
they will try to sync with "d2att" as the device name, but the sync will
not work, as repo only recognizes "d2" as a proper device group. This
commit adds support for syncing with the specific device name.

Please let me know if I missed any device families that need similar
treatment.

UPDATE : fix device/sony/common
