soc: ti: knav_dma: Remove unused DMA_PRIO_MASK macro

DMA_PRIO_MASK (GENMASK(3, 0)) is defined alongside the other priority
macros but is never referenced in the code. tx_priority and rx_priority
are only ever assigned DMA_PRIO_DEFAULT (0) and are never sourced from
device tree or user-controlled input, so no out-of-range value is
possible. W=2 builds report:

  knav_dma.c:32:9: warning: macro is not used [-Wunused-macros]
  32 | #define DMA_PRIO_MASK           GENMASK(3, 0)

Remove the dead macro.
