Previously the vm_configs[] is defined separately for sharing mode and partition mode, but the concept of hypervisor mode will be removed. Instead we will introduce scenario Kconfig for hypervisor to load different vm configurations. SDC(Software Defined Cockpit) is a typical scenario that ACRN supported so we introduce this scenario for previously sharing mode and move its configurations to scenarios/sdc folder. The configuration could be used for all boards reference. Tracked-On: #2291 Signed-off-by: Victor Sun <victor.sun@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
