* The SATA disk topology permits an ASRU to be declared as a pseudo-hc

* hc:///motherboard=0/hostbridge=0/pcibus=0/pcidev=1/pcifn=0/sata-port=1
* ASRU: hc:///component=sata0/1
* FRU: hc:///component=MB
* Label: sata0/1
*
* This is a hack to support cfgadm attachment point ASRUs without defining
* a new scheme. As a result, we need to support an is_present function for
* something * that begins with hc:///component=. To do this, we compare the
* nvlist provided by the caller against the ASRU property for all possible
* topology nodes.
*
* The SATA phase 2 project will address the lack of a proper FMRI scheme
* for cfgadm attachment points. This code may be removed when the SATA
* phase 2 FMA work is completed.
