[PATCH v3 17/19] ARM: dts: microchip: sam9x60: Add OTPC node

[Alexander Dahl]

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:
    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
