dma: tegra: fix interrupt name issue with apb dma.
When watching the interrupts through /proc/interrupts, the name of the interrupts are blank or garbage. The reason is the pointer passed for devname during irq registration is stack and so it get changed after dma registration completes. Allocate the pointer as part of dma channel and pass this pointer as the devname for irq registration to avoid change of name.
