skiboot: Handle combined units node in the imc dt
Add code to detect combined unit nodes
in the imc device tree. Due to HW/OCC restriction
mcs* units are paired and monitored by the nest
microcode. Microcode today does not support monitoring
of individual mcs* unit events, so the patch first
remove these mcs* from the imc device tree if found.
Secondly to enable or disbale combined units nodes like
"mcs01", "mcs23","mcs45" and "mcs67", additional parser
loop is added to disable_unavailable_units().
