Allwinner a83t has a 1 KB sid block with efuse for security rootkey and thermal
calibration data, add node to describe it.
a83t-sid is not currently supported by nvmem/sunxi-sid, but it is
supported in an external driver for FreeBSD.

Pull char/misc updates from Greg KH:
"Here is the big set of char/misc and other driver subsystem patches
for 4.15-rc1.
There are small changes all over here, hyperv driver updates, pcmcia
driver updates, w1 driver updats, vme driver updates, nvmem driver
updates, and lots of other little one-off driver updates as well. The
shortlog has the full details.
All of these have been in linux-next for quite a while with no
reported issues"

Improve the binding example by removing all the leading zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"`
Some unnecessary changes were manually fixed.

Allwinner A64/H5 SoCs come with a SID controller like the one in H3, but
without the silicon bug that makes the initial value at 0x200 wrong, so
the value at 0x200 can be directly read.
Add support for this kind of SID controller.

The H3 SoC have a bigger SID controller, which has its direct read
address at 0x200 position in the SID block, not 0x0.
Also, H3 SID controller has some silicon bug that makes the direct read
value wrong at cold boot, add code to workaround the bug. (This bug has
already been fixed on A64 and later SoCs)

Now that we have the nvmem framework, we can consolidate the common
driver code. Move the driver to the framework, and hopefully, it will
fix the sysfs file creation race.
