[PATCH v2 7/7] musicpal: Use ptimer_free() in the finalize function to avoid memleaks |

When running device-introspect-test, a memory leak occurred in the
mv88w8618_pit_init function, so use ptimer_free() in the finalize function to
avoid it.
ASAN shows memory leak stack:
Indirect leak of 192 byte(s) in 4 object(s) allocated from:
