Subject: [PATCH v5 5/9] power: supply: qcom_battmgr: update compats for
 SM8550 and X1E80100

From: Fenglin Wu <fenglin.wu@....qualcomm.com>

The SM8550 and X1E80100 platforms now include charge control
functionality in battery management firmware, allowing charging
to stop when the battery reaches a set level and resume when it
drops below another level. To support this in the qcom_battmgr
driver, CHARGE_CONTROL_START/END_THRESHOLD power supply properties
can be added to manage these levels. This results in the battery
power supply properties for SM8550 and X1E80100 differing from
those for SM8350 and SC8280XP. Therefore, separate compatible
entries for SM8550 and X1E80100 are introduced, each with
their own variant definitions as match data.
