Sylvain Munaut b2d95779c6 gateware/sysmgr: Make sure sys_start _always_ forces system clock ON 
Before it was only sensitive to rising edge. But for the "start" we
actually want to force it on if active to avoid race condition in the
software where:

- CPU clears the condition of the wakeup
- New wake up event happens right after it
- CPU asks for shutdown
- And then no rising edge happens because wakeup is already high

For shutdown it's good that it's rising edge dependent since the
OFF command signal _might_ stay high if the system clock shuts down
