Add both the cpu and peripheral pl330 dma controllers present in rk3188 socs. The first dma controller can change between secure and non-secure mode and is left by the bootloader in secure mode, which gets added here.

The ePAPR standard [1] says:
The name of a node should be somewhat generic, reflecting the function of the
device and not its precise programming model. If appropriate, the name should
be one of the following choices:
[...]
