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.

Revert "gpio: qcom_pmic: add a quirk to skip GPIO configuration"
This reverts commit 19f000b72b.

The bug in writing was caused by a long-standing error in the SPMI
driver which has since been fixed - c2de620d64 ("spmi: msm: fix
version 5 support"). We can safely enable writing GPIO configuration
now.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

gpio: qcom_pmic: add pinctrl driver
Introduce a basic pinctrl driver for the SPMI PMIC GPIOs. This is
necessary to make proper use of upstream DT bindings specifically on the
dragonboard410c where they're used to switch between USB host and device
modes.

Only support for driving the pins as output low or high is enabled for
now.

To minimise duplicated code and allow for sharing common DT data, the
pinctrl driver is initialised as a child of the existing GPIO driver.

gpio: qcom_pmic: add a quirk to skip GPIO configuration
Some platforms hard reset when attempting to configure PMIC GPIOs. Add
support for quirks specified in match data with a single quirk to skip
this configuration. We rely on the GPIO already be configured correctly,
which is always the case for volume up (the only current user of these
GPIOs).

This is not expected behaviour but appears to be due to a U-Boot
specific bug. This quirk at least allows for the volume buttons to be
used on platforms where this bug is apparent.

Upstream uses the gpio-ranges property to define the number of GPIOs,
support for parsing this when gpio-count is unspecified

Additionally, drop the bank-name property as it isn't used in upstream,
and we can just hardcode the bank name instead.

priv->pid is uint32_t, but dev_read_addr() returns a uint64_t on arm64,

e555d4caac pmic: Convert pm8916 driver to a generic Qcom PMIC driver
Since both pm8916.c and pm8916_gpio.c are already supporting multiple
Qcom SoCs, it makes sense to rename these drivers to pmic_qcom.c and
qcom_pmic_gpio.c respectively. Also, these driver can be extended to
support additional functionality if required for other Qcom SoCs.

Along with this import latest DT binding: qcom,spmi-pmic.txt from Linux
kernel and thereby remove pm8916.txt.
