[RFC PATCH v3 0/3] Add Xiaomi 12 Lite 5G (taoyao) battery support

[Stanislav Zaikin]

Xiaomi 12 Lite 5G (taoyao) has an additional property with ID 12 that
breaks the parsing in qcom_battmgr. Fix that by introducing separate
maps for lookups properties in both directions.

The other approach that I tried is manual shifting properties:

+	if (battmgr->variant == QCOM_BATTMGR_TAOYAO && prop > BATT_CHG_CTRL_LIM_MAX)
+		prop++;
...
+		if (battmgr->variant == QCOM_BATTMGR_TAOYAO && property > BATT_CHG_CTRL_LIM_MAX + 1)
+			property--;

But I found that more obscure.

Will be happy to switch if the maintainers prefer this one.

Changes in v3:
- Fix QCOM_BATTMGR_TAOYAO enum ordering (patch #2)
- Order in qcom_battmgr_of_variants[] is already right (no change)
- Revert the qcom,sm7325-pmic-glink SoC fallback (patch #1 and #3)
- Rephrased commit message (patch #3)
- Design question from v1/v2 still open: lookup tables vs. inline shift

Changes in v2:
- Keep the qcom,sm7325-pmic-glink SoC fallback in the compatible chain
  of the taoyao pmic-glink node (review feedback, patch #1 and #3)
