Extend the API and introduce qmc_chan_get_byphandles_index() and the resource managed version in order to retrieve a channel from a phandle list using the provided index to identify the phandle in the list. Also update qmc_chan_get_byphandle() and the resource managed version to use qmc_chan_get_byphandles_index() and so avoid code duplication.
