HV:Acrn-hypvervisor Root Directory Clean-up and create misc/ folder for Acrn daemons, services and tools.
This patch is to clean-up acrn-hypervisor root directory, targt only 5 folders under acrn-hypervisor:1.hypervisor,2.devicemodel,3.misc,4.doc,5.build Tracked-On: #3482 Signed-off-by: Terry Zou <terry.zou@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
