Add 8250 UART APDMA to support MediaTek UART. If MediaTek UART is enabled by SERIAL_8250_MT6577, and we can enable this driver to offload the UART device moving bytes.

Support for the UART DMA engine found on MediaTek MTK SoCs.
|
|
When SERIAL_8250_MT6577 is enabled, and if you want to use DMA,
|
|
you can enable the config. The DMA engine can only be used
|
|
with MediaTek SoCs.
