Add a CONFIG_SIMULAVR option to the Kbuild menus and don't directly prompt users for CONFIG_WATCHDOG or CONFIG_SERIAL_BAUD_U2X. The only reason to disable these options would be if one were running on simulavr. This simplifies the user visible menu options. Also, only show CONFIG_CLEAR_PRESCALER for at90usb1286 chips.
