ARM: dts: nxp: imx6ul: correct SAI3 interrupt line

The i.MX6UL reference manual lists two possible interrupt lines for
SAI3 (56 and 57, offset +32). The current device tree entry uses
the first one (24), which prevents IRQs from being handled properly.

Use the second interrupt line (25), which does allow interrupts
to work as expected.
