mtd: rawnand: remove unecessary checking if dmac is NULL
Remove unecessary checking if dmac is NULL.
If Cadence nand controller driver uses DMA engine then cdns_ctrl->dmac
cannot be NULL. It is verified during driver initialization.
If Cadence nand controller driver does not use DMA engine then
CPU IO read/write are executed instead of slave DMA transfer.
In that case cdns_ctrl->dmac is not used at all.
