gpio: qcom_pmic: add again the quirk to skip GPIO configuration on PM8550

The qcom_pmic code is broken for new PMICs and should be fixed,
without the QUIRK the code is broken and the GPIOs don't work
anymore on SM8550 and SM8650 platforms.

Partially revert the revert and only add the quirk on the PM8550
PMIC, making the buttons and MMC detect gpio work again.
