tidspbridge: convert to idr_alloc()

idr_get_new*() and friends are about to be deprecated.  Convert to the
new idr_alloc() interface.

There are some peculiarities and possible bugs in the converted
functions.  This patch preserves those.

* drv_insert_node_res_element() returns -ENOMEM on alloc failure,
  -EFAULT if id space is exhausted.  -EFAULT is at best misleading.

* drv_proc_insert_strm_res_element() is even weirder.  It returns
  -EFAULT if kzalloc() fails, -ENOMEM if idr preloading fails and
  -EPERM if id space is exhausted.  What's going on here?

* drv_proc_insert_strm_res_element() doesn't free *pstrm_res after
  failure.

Only compile tested.
