hw-mgmt: system events: ASIC init complition done

Add two new attributes:
/var/run/hw-management/config/asic_chipup_completed
/var/run/hw-management/config/asics_init_done

'asic_chipup_completed' carries counter of completed ASIC devices
probing.
'asics_init_done' is to be set to one, when 'asic_chipup_completed'
attribute matches 'asic_num' attribute.

Motivation is to use 'asics_init_done' as criteria of system
infrastructure readiness.
