nvmem: add explicit config option to read old syntax fixed OF cells
Binding for fixed NVMEM cells defined directly as NVMEM device subnodes
has been deprecated. It has been replaced by the "fixed-layout" NVMEM
layout binding.
New syntax is meant to be clearer and should help avoiding imprecise
bindings.
NVMEM subsystem already supports the new binding. It should be a good
idea to limit support for old syntax to existing drivers that actually
support & use it (we can't break backward compatibility!). That way we
additionally encourage new bindings & drivers to ignore deprecated
binding.
It wasn't clear (to me) if rtc and w1 code actually uses old syntax
fixed cells. I enabled them to don't risk any breakage.

nvmem: microchip-otpc: add support
Add support for Microchip OTP controller available on SAMA7G5. The OTPC
controls the access to a non-volatile memory. The memory behind OTPC is
organized into packets, packets are composed by a fixed length header
(4 bytes long) and a variable length payload (payload length is available
in the header). When software request the data at an offset in memory
the OTPC will return (via header + data registers) the whole packet that
has a word at that offset. For the OTP memory layout like below:
offset OTP Memory layout
. .
. ... .
. .
0x0E +-----------+ <--- packet X
| header X |
0x12 +-----------+
| payload X |
0x16 | |
| |
0x1A | |
+-----------+
. .
. ... .
. .
if user requests data at address 0x16 the data started at 0x0E will be
returned by controller. User will be able to fetch the whole packet
starting at 0x0E (or parts of the packet) via proper registers. The same
packet will be returned if software request the data at offset 0x0E or
0x12 or 0x1A.
The OTP will be populated by Microchip with at least 2 packets first one
being boot configuration packet and the 2nd one being temperature
calibration packet. The packet order will be preserved b/w different chip
revisions but the packet sizes may change.
For the above reasons and to keep the same software able to work on all
chip variants the read function of the driver is working with a packet
id instead of an offset in OTP memory.
