usb: dwc2: Remove unnecessary prototypes
Remove the unnecessary prototypes for all the parameter setting functions and declare those functions 'static' in the params.c file. Also remove the duplicate documentation that went along with them. They are already documented as part of the params structure definition. Then move the constants that went along with the prototype into the structure.
