[PATCH 0/7] dts: Add and use UART AP_DMA controller on MTK SoCs

First of all: not all of them will use this and that's sure - but the
devicetree describes hardware, and this hardware was not described on
any of the SoCs that support the UART AP_DMA controller.

Besides, there is also driver support for this controller for all SoCs!

Let's add support for this IP in all of the SoCs that have it.
