gpiolib-acpi: Preserve non direction flags when updating gpiod_flags
__acpi_gpio_update_gpiod_flags purpose is to make the gpiod_flags used when requesting a GPIO match the restrictions from the ACPI resource, as stored in acpi_gpio_info.flags. But acpi_gpio_info.flags only contains direction info, and the requester may have passed in special non-direction flags like GPIOD_FLAGS_BIT_NONEXCLUSIVE, which we currently clobber. This commit modifies __acpi_gpio_update_gpiod_flags to preserve these special flags, so that a requested of an ACPI GPIO can e.g. pass GPIOD_FLAGS_BIT_NONEXCLUSIV and have it work as intended.
