gnss: sirf: add support for configurations without wakeup signal

Some Wi2Wi devices do not have a wakeup output, so device state can
only be indirectly detected by looking whether there is communication
over the serial lines.
This approach requires a report cycle set to a value less than 2 seconds
to be reliable.
