ASoC: stm32: i2s: fix registers declaration in regmap
- Declare SR as volatile, as it is changed by hardware. - Remove TXDR from readable and volatile register list, as it is intended for write accesses only. Signed-off-by: Olivier Moysan <olivier.moysan@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>
