ASoC: mediatek: mt8192: Release reserved memory on cleanup

Browse source

The MT8192 AFE probe calls of_reserved_mem_device_init() and falls
back to preallocated buffers when no reserved memory region is
available. When the reserved memory assignment succeeds, however, the
driver never releases it.

Register a devm cleanup action after a successful reserved-memory
assignment so the assignment is released on probe failure and driver
unbind.
