hw/misc/mps2-scc: Free MPS2SCC::oscclk[] array on finalize()

Commit 0be6bfac62 ("qdev: Implement variable length array properties")
added the DEFINE_PROP_ARRAY() macro with the following comment:

  * It is the responsibility of the device deinit code to free the
  * @_arrayfield memory.

Commit 4fb013afcc added:

  DEFINE_PROP_ARRAY("oscclk", MPS2SCC, num_oscclk, oscclk_reset,
                    qdev_prop_uint32, uint32_t),

but forgot to free the 'oscclk_reset' array. Do it in the
instance_finalize() handler.
