allwinner: Return the PMIC to I2C mode after use
This gives the rich OS the flexibility to choose between I2C and RSB communication. Since a runtime address can only be assigned once after entering RSB mode, it also lets the rich OS choose any runtime address. Signed-off-by: Samuel Holland <samuel@sholland.org> Change-Id: Id49c124c5e925985fc31c0ba38c7fb6c941aafa8
