HSU (High Speed UART) DMA engine, like the name suggests, is an integrated DMA engine for UART and UART alone. Therefore, making the UART drivers responsible of selecting it and removing the user selectable option for it. The UARTs with this DMA engine can always select HSU_DMA when SERIAL_8250_DMA option is enabled.
