Add support for the RT9471 3A 1-Cell Li+ battery charger.

The RT9471 is a highly-integrated 3A switch mode battery charger with
low impedance power path to better optimize the charging efficiency.

You need to document the sysfs ABI in Documentation.

Can it be define in 'sysfs-class-power' or a dedicated file called
'sysfs-class-power-rt9471'?
Not sure which one is better.

I don't know what is Sebastian's preference. You can wait for his input
or do similarly as last patches reviewed/picked up by him.

M... OK.
Whatever the preference is, at least, I can prepare the ABI contents first.

Best regards,
