[PATCH v2 13/16] 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.
