Aseda Aboagye 61a6a3814f bq24392: Make chip_en active low. ...

The GPIO that turns on Vbus for the BQ24392 is active low.  This commit
changes the driver to make it clear that the enable is active low.
Additionally, the 5V rail is turned on prior to performing detection and
will be turned off if the AP is off.

For zoombini, since the chipset task can also control the 5V rail,
CONFIG_POWER_PP5000_CONTROL is enabled to do so in a task-safe way.

BUG=b:65992382, b:65991615
BRANCH=None
TEST=Verify that Vbus is turned on and the BQ24392 can output high on
charge detect pin.
