app: boards: imx95: switch to using nxp,edma driver

Zephyr commit 774370a1d712 ("boards: nxp: imx95_evk_mimx9596_m7: add uart
dma support") replaces the configuration of the "edma2" node with that
mandated by the programming model associated with the "nxp,mcux-edma"
compatible. This change was done because the EDMA driver associated with
said compatible is compatible with multiple peripheral drivers as opposed
to the previous "nxp,edma" driver.

However, SOF currently requires using the previous EDMA driver (i.e. the
one associated with the "nxp,edma" driver). Therefore, switch back to the
previous programming model.

Furthermore, the DMA channels used by the SAI IP were also changed. Since
these were not tested, switch back to the previous DMA channels.
