Fix unbalanced error handling path which will get incorrect counts
if probe failed. The .remove() should be adjusted accordingly.

Reworks mt2701-afe-clock* to make it more reasonable and flexible.
Hence current changes are:
- Replace regmap operations by CCF APIs. Doing so, we just need to handle
the child/element clocks - we can also get accurate information via CCF.
- Rename clock names to make them more generic just in case the future
revisions of the IP can adapt gracefully and remove unused ones.
- Split up 'aud_clks[]' into two by usage - the basic needs and I2S parts.
Currently we put all clocks together in array, so change the code to
just keep the shared clocks in array.
As for I2S parts, we still use MT2701_I2S_NUM in driver now. There might be
other chips that use the same driver and therefore we will add a little more
abstract if we have different sets of channels in future.
Moreover, this patch moves I2S clocks to the struct mt2701_i2s_data
so that we can easily manage them when calls .prepare() and .shutdown().

Add 'assigned-clocks*' properties which are used to initialize default
domain sources of audio system. we could configure different sets of
input clocks through DTS now - depends on the platform design. Hence
driver no longer cares about that.
Also we change some 'clock-names' to make them more generic so that
other chips can reuse gracefully.
