Pali Rohár c8b00da695 arm: mvebu: a37xx: Add support for reading Security OTP values 
It is not possible for the A53 core (on which U-Boot is running) to read it
directly. For this purpose Marvell defined mbox API for sending OTP
commands between CM3 and A53 cores.

Implement these Marvell fuse reading mbox commands via U-Boot fuse API.

Banks 0-43 are used for accessing Security OTP (44 rows with 67 bits via 44
banks and words 0-2).

Note that of the 67 bits, the 3 upper bits are: 1 lock bit and 2
auxiliary bits (meant for testing during the manufacture of the SOC, as
I understand it).

Also note that the lock bit and the auxiliary bits are not readable
via Marvell commands.

With CZ.NIC's commands the lock bit is readable.

Write support is not implemented yet.
