pl031: Use timer_free() in the finalize function to avoid memleaks
When running device-introspect-test, a memory leak occurred in the pl031_init
function, this patch use timer_free() in the finalize function to fix it.
ASAN shows memory leak stack:
Direct leak of 48 byte(s) in 1 object(s) allocated from:
