mfd: max8997: Naturalise cross-architecture discrepancies

If we compile the MAX8997 for a 64bit architecture we receive the following
warnings:

  drivers/mfd/max8997.c: In function ‘max8997_i2c_get_driver_data’:
  drivers/mfd/max8997.c:173:10:
    warning: cast from pointer to integer of different size
     return (int)match->data;
            ^
