- Reworks Qualcomm support to be more generic, dropping board specific
build targets and relying on DT as the only source of truth
- Switches all Qualcomm devices to use upstream devicetree

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.

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.

Qualcomm PMICs number their GPIOs starting from 1, implement a custom
.xlate method to handle this.

This property is not part of the dt bindings and all boards use the new
gpio-ranges property instead. Drop support for this.

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.

Remove the (now unused) GPIO driver for the power and resin buttons on
the PMIC.

priv->pid is uint32_t, but dev_read_addr() returns a uint64_t on arm64,
with the upper bits being used for error codes. Do error checking before
downcasting to u32 to prevent errors being silently ignored.

GPIO button driver requires direction functions to probe
button gpio. Those functions are blank, since pwrkey is not
really gpio, and don't support direction settings.

GPIO LV (low voltage)/MV (medium voltage) subtypes have different
features and register mappings than 4CH/8CH subtypes. Add support
for LV and MV subtypes.
With GPIO LV/MV subtype available, add "qcom,pms405-gpio" compatible
which requires support for GPIO MV subtype.

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.
