ASoC: meson: aiu-encoder-i2s: use the core symmetric_rate handling

Browse source

The driver manually implement the interface-wide rate symmetry enforcement
in hw_params(), which suffers from the same problem addressed in the
previous patch: the restriction is not visible in the hw parameter
constraints, so a stream with a mismatching rate only finds out via
-EINVAL late in the stream setup.

The ASoC core already provides this feature through the DAI's
'symmetric_rate' flag: when another stream of the DAI is active,
soc_pcm_apply_symmetry() constrains the rate at open time so the
restriction shows up during parameter refinement, and
soc_pcm_params_symmetry() still rejects a mismatch at hw_params()
time as a backstop.

Set 'symmetric_rate' on the I2S encoder DAI and drop the open-coded
check along with the now unused 'rate' member of struct gx_iface.
