schematic: mark USB reset circuit as dot no place

Browse Source

the additional circuit to reset USB (by pulling D+ low) is not
required anymore since the USB controller in the SAM3S integrates
this capability.
the SAM3S-EK Development Board also demonstrates only the inline
27 Ohm termination resistors are required.

this change has been tested (behind 2 USB HUBs).
the RESET button still works.
resetting using DFU into the bootloader and starting the
application from the bootloader still works.
