[U-Boot] [PATCH 1/2] power: as3722: Allow using on any i2c bus with any address

From: Alban Bedel <alban.bedel at avionic-design.de>

The init simply hardcoded the i2c bus and address to those used on
jetson. Extend the init function to take the bus number and device
address as parameter. As only jetson is using this code for now just
fix this single use of the function.
