Remove some unused CONFIG_* variables

There are a few CONFIG_* variables defined in default-configs/ that are never referenced. These were found using:

 $ for i in `grep -h -E '^CONFIG' default-configs/*  | sed -e 's/=.*//' | sort | uniq`
 do
     echo -n "$i: "
     git grep $i | grep -v default-configs | wc -l
 done | grep  ": 0"
 CONFIG_IPMI_EXTERN: 0
 CONFIG_ISA_MMIO: 0
 CONFIG_PAM: 0
 CONFIG_PIIX_PCI: 0

NB, the IPMI_EXTERN one is special - it should have been used, so I sent a separate patch for that one.

Daniel P. Berrange (3):
default-configs: remove CONFIG_PAM
default-configs: removed obsolete CONFIG_ISA_MMIO
default-configs: remove CONFIG_PIIX_PCI
