ASoC: topology: Allow TLV control to be either read or write

commit feb00b736af64875560f371fe7f58b0b7f239046 upstream.

There is no reason to force readwrite access on TLV controls. It can be
either read, write or both. This is further evidenced in code where it
performs following checks:
                if ((k->access & SNDRV_CTL_ELEM_ACCESS_TLV_READ) && !sbe->get)
                        return -EINVAL;
                if ((k->access & SNDRV_CTL_ELEM_ACCESS_TLV_WRITE) && !sbe->put)
                        return -EINVAL;

Fixes: 1a3232d2f61d ("ASoC: topology: Add support for TLV bytes controls")
