DMA: PL330: move filter function into driver
The dma channel selection filter function is moved from plat-samsung into the pl330 driver. In additon to that, a check is added in the filter function to ensure that the channel on which the filter has been invoked is pl330 channel instance (and avoid any incorrect access of chan->private in a system with multiple types of DMA drivers).
