Doc: qemu cmdline update for acrn on qemu
For platforms which have apicv post-interrupt capability; ACRN would use posted-interrupt to notify another vCPU which in non-root mode; or sync interrupt for itself when it in root-mode.However,QEMU could not handle this properly. So, remove the post-interrupt capability in qemu cmdline. Signed-off-by: fuzhongl <fuzhong.liu@intel.com> Reviewed-By: Li, Fei <fei1.Li@intel.com>
