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