This patch provides basic support for booting with ACPI instead
of the currently supported Device Tree. When doing so there are a
couple of differences which we need to taken into consideration.
Firstly, the SDM850 ACPI tables omit information pertaining to the
4 reserved GPIOs on the platform. If Linux attempts to touch/
initialise any of these lines, the firmware will restart the
platform.
Secondly, when booting with ACPI, it is expected that the firmware
will set-up things like; Regulators, Clocks, Pin Functions, etc in
their ideal configuration. Thus, the possible Pin Functions
available to this platform are not advertised when providing the
higher GPIOD/Pinctrl APIs with pin information.
