§Abstractions to setup and use the DMA controller

The DMAC should be initialized using the DmaController::init method. It will consume the DMAC object generated by the PAC. By default, all four priority levels will be enabled, but can be selectively enabled/disabled through the DmaController::enable_levels ansd DmaController::disable_levels methods.

Using the DmaController::split method will return a struct containing handles to individual channels.

Using the free method will deinitialize the DMAC and return the underlying PAC object.

Channels: Struct generating individual handles to each DMA channel
DmaController: Initialized DMA Controller
FutureChannels: Struct generating individual handles to each DMA channel for async operation
PriorityLevelMask: Mask representing which priority levels should be enabled/disabled
RoundRobinMask: Mask representing which priority levels should be configured as round-robin
