Quite a few codecs can run at 192kHz, although I'm not aware of many SoC
CPU's that will support 192kHz I2S. Your best bet is using a SoC CPU
with a multi-function port (that also does I2S) as they tend to support
faster transfer rates (e.g. SSP on pxa, SSI on i.MX).

I guess 192kHz is missing from ASoC atm because there is no supported
codec hardware that needs it. Trivial to add.
