ASoC: mediatek: mt8183: Release reserved memory on cleanup

Browse Source 
The MT8183 AFE probe can assign reserved memory with
of_reserved_mem_device_init(), but the assignment is never released on
driver removal or later probe failures.

Register a devm cleanup action so the reserved memory assignment is
released consistently, matching newer Mediatek AFE drivers.

Fixes: ec4a10ca4a ("ASoC: mediatek: use reserved memory or enable buffer pre-allocation")
