ASoC: codec: rt286: Use devm_request_threaded_irq to manage IRQ lifetime and fix smatch warning

Browse source 
Replace manual "request_threaded_irq()" with the device managed
"devm_request_threaded_irq" to manage the IRQ lifetime and also
it removes the smatch reported warning.
Remove the manual "free_irq()" in the "remove" function as free_irq
is tied to device teardown.
