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

stable inclusion

commit 74f7971985bd06aea710cc5ed5f01d94ac3fc9fd
bugzilla: https://gitee.com/openeuler/kernel/issues/I574AL

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=74f7971985bd06aea710cc5ed5f01d94ac3fc9fd



--------------------------------

commit feb00b73 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;
