drivers: usb: add usb device driver support for NPCM4XX series.

1. add npcm4xx usb device driver. 2. add npcm4xx usb device register define in reg_def.h 3. disable build i3c driver temporarily. 4. enable stack overflow checking. 5. configure the main stack size from 1024 to 2048. 6. disable compiler optimization as default.
