Presumably this patch to the device tree file should go through the
Qualcomm tree.  Now that bindings have been reviewed by Rob it could
probably land any time.

Changes in v5: None
Changes in v4:
- Clock name is "core", not "sec".

Changes in v3:
- Name is now 'efuse' to match what schema checker wants.
- Reorganized ranges to match driver/bindings changes.
- Added 4th range as per driver/binding changes.
- No more reg-names as per driver/binding changes.
- Clock name is now just "sec" as per driver/binding changes.
