Subject: [PATCH v2 0/8] power: supply: Add several features support in
 qcom-battmgr driver

Add following features in qcom-battmgr drivers as the battery management
firmware has provided such capabilities:
 - Add resistance power supply property in core driver and qcom-battmgr
   driver to get battery resistance
 - Add state_of_health power supply property in core driver and
   qcom-battmgr driver to get battery health percentage
 - Add charge control start/end threshold control by using
   charge_control_start_threshold and charge_control_end_threshold power
   supply properties

The changes have been tested on QRD8650 and X1E80100-CRD devices based on
qcom/linux.git for-next commit f8d04825b12f42ec8198dee1ab4654792f9ac231.

Changes in v2:
- Corrected "qcom-battmgr" to "qcom_battmgr" in the commit subject of
  patch 4/5.
- Added charge control support for X1E80100 platform in patch 5.
- X1E80100 is no longer a fallback of SM8550 in pmic-glink battmgr support,
  hence added patch 6 in the pmic-glink binding to move X1E80100 out of the
  fallbacks.
- Added patch 7 in glink-ucsi driver to include UCSI quirk for X1E80100
  platform
- Added patch 8 to remove "qcom,sm8550-pmic-glink" compatible string in
  x1* board files.
- Rebased the changes on qcom/linux.git for-next commit 44ef9ab4baaf496d227ab98d368016700f0b9300.
- Link to v1: https://lore.kernel.org/r/20250523-qcom_battmgr_update-v1-0-2bb6d4e0a56e@oss.qualcomm.com
