[PATCH] mfd: tc3589x: Use devm_request_threaded_irq() to fix the missing undo bug

[Chuhong Yuan]

This driver calls request_threaded_irq() in probe, but it misses calling
free_irq() in probe's error handler and remove.
Replace request_threaded_irq() with the devm version to fix it.

Fixes: 20406ebff4a2 ("mfd/tc3589x: rename tc35892 structs/registers to tc359x")
