usb: mv_udc: Clean up the EP initialization

Browse Source 
Move the constant values that are programmed into mv_ep.ep into
separate static const structure so they can be memcpy()'d when
the initialization happens.

Moveover, we only every init NUM_ENDPOINTS, not 2 * NUM_ENDPOINTS,
so fix this bug as well.
