i2c: ismt: Use minimum descriptor size
Software is allowed to allocate number of descriptor size from 2 to 256,
this i2c controller could process more descriptor, but for i2c core soft
ware layer, only one i2c transaction is allowed each time.
So here switch to minimum 2 descriptor when initialization.
