drivers/uart/acpi: Drop 'disable_gpio_export_in_crs' flag
Exposing the GPIOs via an ACPI PowerResource and the _CRS results in the OS driver and ACPI thinking they own the GPIO. This can cause timing problems because it's not clear which system should be controlling the GPIO. There's no reason to require explicit disablement however, so drop the superfluous 'disable' flag, and change the _CRS generation to check if the GPIOs will be exported via the 'has_power_resource' flag instead. This mirrors the change made for drivers/i2c/generic. TEST=untested, as no boards selected this option.
