DM: VMcfg: Kconfig & Makefile for VM Configuration

Browse Source 
VMcfg use Kconfig mechanism to generate a header file
devicemodel/include/vmcfg_config.h, which contains many macro symbols
for conditionally compiling. This feature is disabled by default, to
enable it, You can switch to devicemodel/vmcfg/ and run 'make' with
these options:

'make menuconfig'
run 'make menuconfig' at ./devicemodel/vmcfg/, and configure manually.
When you finished, save your changes to ./devicemode/vmcfg/.config

'make oldconfig'
Overwrite ./devicemodel/vmcfg/.config with your config file, then run
'make oldconfig' at ./devicemodel/vmcfg

'make *_defconfig'
E.g, there is ./devicemodel/vmcfg/config/mrb_defconfig, you can run
'make mrb_defconfig' at ./devicemodel/vmcfg/
