[PATCH v2] gpio: qcom_spmi_gpio: move PM8998 GPIO from legacy pmic driver

[Petr Hodina via B4 Relay]

From: Petr Hodina <petr.hodina at protonmail.com>

Move the "qcom,pm8998-gpio" compatible from the legacy driver
qcom_pmic_gpio.c to qcom_spmi_gpio.c. Enables on PM8998-based boards
(sdm845: SHIFT 6mq, Pixel 3, OnePlus 6, Poco F1, Sony Xperia Akatsuki)
the Volume UP gpio-key.

Changes in v2:
- Reworked per Neil Armstrong's suggestion on v1: migrate PM8998 to the
  modern qcom_spmi_gpio driver instead of extending the legacy
  qcom_pmic_gpio.c.
- Dropped "gpio: qcom_pmic_gpio: implement standard pinconf parameters".
- Dropped "gpio: qcom_pmic_gpio: don't reset pull on direction change".
- Replaced with a single qcom_spmi_gpio.c patch that claims the
  qcom,pm8998-gpio compatible.
- Link to v1: https://patch.msgid.link/20260601-qcom-gpio-v1-0-e24bcdb35da0@protonmail.com
