[PATCH v3] ARM: dts: sunxi: Add sid for a83t

[kevans at FreeBSD.org]

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.
