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.
