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 poked through the ASoC code and could only see 96khz capability.
I guess 192kHz is missing from ASoC atm because there is no supported codec hardware that needs it. Trivial to add.
