uart_sam0: don't consume CONFIG_UART_ASYNC_API directly.
There are situations in which the async API for uart can be provided by another driver (case in point, uart_rtt), and thus there is no valid DMA controller for the uart_sam0 driver to talk with. By separating the configuration, there's no need to exclude samd20-based boards (that have no DMA peripheral) from the uart_async_api tests.
