Add the pinctrl driver for the Qualcomm Technologies QDF2xxx ARM64 SoCs,
which uses the Qualcomm Technologies TLMM pinctrl/gpio device.  This
driver is probed via ACPI and uses the pinctrl-msm.c backend driver.

This driver is intended to be used only an ACPI-enabled system.  As such,
UEFI will handle all pin control configuration, so this driver does not
provide pin control functions.  It is effectively a GPIO-only driver.

In my experience, you will come back and add pin control to it if
it ever sees any practical power-aware use cases.

For the same reason that Intel is doing it to their pin controllers,
that also run on systems that are ACPI-enabled.
