I'm not really convinced that platform data is the right way to pass such 
data.

IMHO driver/match data were supposed to contain variant-specific 
parameters, which the driver would receive based on matching platform 
device name (in non-DT case) or compatible string (in DT case).

Best regards,
Tomasz
