Fenglin Wu 13276961ae power: supply: qcom_battmgr: handle charging state change notifications 
[ Upstream commit 41307ec7df ]

The X1E80100 battery management firmware sends a notification with
code 0x83 when the battery charging state changes, such as switching
between fast charge, taper charge, end of charge, or any other error
charging states.

The same notification code is used with bit[8] set when charging stops
because the charge control end threshold is reached. Additionally,
a 2-bit value is included in bit[10:9] with the same code to indicate
the charging source capability, which is determined by the calculated
power from voltage and current readings from PDOs: 2 means a strong
charger over 60W, 1 indicates a weak charger, and 0 means there is no
charging source.

These 3-MSB [10:8] in the notification code is not much useful for now,
hence just ignore them and trigger a power supply change event whenever
0x83 notification code is received. This helps to eliminate the unknown
notification error messages.
