It is convenient to be able to adjust some of the flags for a GPIO while leaving others alone. Add a function for this.
Update dm_gpio_set_dir_flags() to make use of this.
Also update dm_gpio_set_value() to use this also, since this allows the open-drain / open-source features to be implemented directly in the driver, rather than using the uclass workaround.
Update the sandbox tests accordingly. This involves a lot of changes to dm_test_gpio_opendrain_opensource() since we no-longer have the direciion being reported differently depending on the open drain/open source flags.
Also update the STM32 drivers to let the uclass handle the active low/high logic.
Drop the GPIOD_FLAGS_OUTPUT() macro which is no-longer used.

Applied to u-boot/next, thanks!
