Although, I think you are possibly missing some other properties for
i2s mode like word size and master/slave mode. I think the ideal case
is that a single ASoC platform driver for DT could handle multiple
SoCs.

No.  You're not going to be able to get a single binding which handles
the setup for all systems based off a given SoC let alone multiple SoCs.
It is possible to come up with some subsets which work over multiple
boards but that's going to be outside the binding for the I2S controller
and in a board audio hardware binding for the subset.

This has been discussed repeatedly, we really need to work out how to
educate device tree people about this stuff, it gets *very* repetitive
having the discussion over and over again.
