The One-Time Programmable (OTP) Memory Controller (OTPC) is the secure
interface between the system and the OTP memory. It also features the
Unique Product ID (UID) registers containing a unique serial number.
See datasheet (DS60001579G) sections "7. Memories" and "23. OTP Memory
Controller (OTPC)" for reference.

Notes:
v4:
- Dropped new microchip,sam9x60-otpc compatible,
use microchip,sama7g5-otpc instead
v3:
- Removed needless header include
- Removed clock-names, not part of bindings anymore, and not used by driver
v2:
- squashed with patch adding the clock properties
