bmi260: Set i2c transfer size to 128
This change only applies to kukui firmware branch.
To support i2c transfer with chunk large than 255 bytes, the change
8f8d017fb3 ("i2c_master: extend i2c_xfer_no_retry..") is needed. To
minimize the changes needed, this CL modifies BMI260's transfer chunk
size to 128.
