6.17-stable review patch. If anyone has any objections, please let me know.

commit 1b03346314b791ad966d3c6d59253328226a2b2d upstream.
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.
