The Smart Battery Specification v1.1 defines Manufacture Date as one of
its availabe registers. This patch adds this as a property so that
power_supply drivers can support the property and report it in syfs.

Hi,
Support for SBS battery manufacturer date is part of power-supply's
pull request for v5.8 with a different API allowing other batteries
to expose less precise information:
