will, depending on what the user sets in battery settings UI.
* Disabling fast charge may be useful for reducing the heat produced by
the device while charging, or for extending the lifespan of the battery
* This commit introduces the fastcharge HIDL, which writes in the node
/sys/class/sec/switch/afc_disable
0 or 1 depeding on user selection.
0 means that fastcharge is enabled, while 1 means that fastcharge is
disabled
