power: supply: move HDQ interface for bq27xxx from w1 to power/supply
The HDQ interface driver should be in this folder just like the I2C interface driver. Move this driver out of drivers/w1/slave and into drivers/power/supply. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Pali Rohár <pali.rohar@gmail.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
