cmd/dma: implement dmareset command

This adds a new U-Boot command 'c5_pl330_dma' for Cyclone V SoCDK
boards. It provides access to the Reset Manager's Per2ModRst register
to release the reset for ARM PrimeCell PL330 DMA channels. This allows
software to initialize and use the PL330 DMA controller properly after
reset.
