Subject: [PATCH backport] firmware: dmi: Add access to the SKU ID string
backport

Backport of two below upstream commits.

commit b23908d3c48a37c46c6a26df2cdeab1610b360ba
Author: Simon Glass <[email protected]>
Date: Sun Jun 17 14:09:42 2018 +0200

firmware: dmi: Add access to the SKU ID string

This is used in some systems from user space for determining the
identity
of the device.

Expose this as a file so that that user-space tools don't need to
read
from /sys/firmware/dmi/tables/DMI
