greybus: hd: Add API to release reserved CPorts
It is required to release all unique ids registered via ida_get_simple
to avoid any possible memory leak. cport_release() already exists with
special handling for ES2_CPORT_CDSI1, i.e. updating in_use flag without
removing associated ida.
So, added another API to release reserved cports CDSI0 and CDSI1. This
is intended to be used only during es2_destroy().
