ab8500-bm: Add usb power path support
AB8540 supports power path function in USB charging mode for fast power up with dead and weak battery, and it could extend the battery age. When USB charging starts, if the Vbattrue is below than SW cut off voltage, power path and pre-charge should be enabled. If Vbattrue is higher than SW cut off voltage, power path and pre-charge should be disabled. This is to make sure full current to battery charge. At the end of charge, power path should be enable again to reduce charging the battery again. Signed-off-by: Lee Jones <lee.jones@linaro.org>
