[ion] 26677: - Add more code to CmpInitializeMachineDependentConfiguration to create the BIOSINFO key and to start working on the CentralProcessor key (which, in ReactOS, FreeLDR creates when it shouldn't). Creates the basic CentralProcessor nodes for now. - Add cmconfig.c and implement a helper routine that converts from ARC CONFIGURATION_COMPONENT_DATA to a Hardware Description entry and resource descriptor. - Fix outdated _CONFIGURATION_TYPE definition in our DDK.

New Revision: 26677

URL: http://svn.reactos.org/svn/reactos?rev=26677&view=rev
Log:
- Add more code to CmpInitializeMachineDependentConfiguration to create the BIOSINFO key
and to start working on the CentralProcessor key (which, in ReactOS, FreeLDR creates when
it shouldn't). Creates the basic CentralProcessor nodes for now.
- Add cmconfig.c and implement a helper routine that converts from ARC
CONFIGURATION_COMPONENT_DATA to a Hardware Description entry and resource descriptor.
- Fix outdated _CONFIGURATION_TYPE definition in our DDK.
