soc/apl: add options to override USB port config
Allows to override the PortUsb20Enable and PortUsb30Enable FSP options
(which are set to 1 by default) to enable/disable USB ports if the
usb_config_override flag is set to "1". Therefore, these changes will
not affect other boards with an Apollo Lake processor.
