The driver doesn't report an error message if the ACPI tables are missing
the num-gpios property (which indicates how many GPIOs there are on this
SOC), and it didn't check to ensure that the mallocs didn't fail.

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.
