usb_port_power: Use same name for mode set function
usb_port_power: Use same name for mode set function

Dumb USB ports do not have the same notion of charge mode as smart
ports. However, the header common/usb_charge.h declares a function for
changing charge mode that the dumb USB port power implementation does
not define. Instead, it defines a similar function with a different
name, albeit with other allowed values for its second parameter.

This patch makes the names the same so the function can be used by
simply including the aforementioned header file.
