dmaengine: dw-axi-dmac: Fix CH_CFG2 channel priority position
The CH_CFG2 channel priority field occupies bits 51:47 of the 64-bit
channel configuration register, corresponding to bits 19:15 of CH_CFG2_H.
The driver currently shifts the priority value by 20, programming the
wrong bits. Use bit 15 as the field position.
