This set addresses problems observed with the CLAIM tag feature.  The first
patch adds support for CLAIM tags to the ETB10 drivers.  The remaining 3 
patches deal with properly handling the tags on ETF and ETM3x devices.

Regards,
Mathieu

Changes since V1:
* Added Suzuki's review tags to patch 1 and 2.
* Addressed ordering issued in ETM3x enable/disable functions (Leo Yan)
