platform/x86: mlx-platform: Change API for i2c-mlxcpld driver activation
Activate 'i2c-mlxcpld' driver with 'platform_device_register_resndata' instead off 'platform_device_register_simple' in order to pass platform specific info. Add platform i2c data for the next generation systems. Signed-off-by: Vadim Pasternak <vadimp@mellanox.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
