spi: add devm_spi_new_ancillary_device()

Add a devres-managed version of spi_new_ancillary_device() that
automatically unregisters the ancillary SPI device when the parent
device is removed.

This follows the same devm_add_action_or_reset() pattern used by the
other managed SPI functions (devm_spi_optimize_message,
devm_spi_register_controller, etc.) and eliminates the need for drivers
to open-code their own devm cleanup callbacks for ancillary devices.
