USB: support Huawei data card product IDs
In this patch, we want to do one thing: add more Huawei product IDs into the USB driver. Then it can support more Huawei data card devices. So to declare the unusual device for new Huawei data card devices in unusual_devs.h and to declare more new product IDs in option.c. To modify the data value and length in the function of usb_stor_huawei_e220_init in initializers.c That's because based on the USB standard, while sending SET_FETURE_D to the device, it requires the corresponding data to be zero, and its sending length also must be zero. In our old solution, it can be compatible with our WCDMA data card devices, but can not support our CDMA data card devices. But in this new solution, it can be compatible with all of our data card devices.
