[Libvirt-cim] [PATCH 0 of 4] Add ResoucePool support for input and graphics devices

[Kaitlin Rupert]

Having a resource pool for both input and graphics devices doesn't really make 
sense (as we won't be allocating these devices from a pool).  But a pool 
instances is need to get the AC instances, which is then used to get the 
template RASDs of a device.  

So, for consistency with other devices, pools for graphics and input devices is
added here.
