pass: rescon: Separate pass-rescon module from pass-gov module

The existing pass-gov module has the three features as following:
- Resource Controller to change the current/min/max 'PASS Level' -> rescon.
- Resource Monitor to collect the current system status -> resmon.
- Runtime governor for CPU hotplug policy.

In order to make the pass-rescon as the separate module,
this patch creates the pass-rescon.c module from pass-gov module separately.
