rockchip平台关闭硬件加速 vendor.hwc.compose_policy

修改位置：

device/rockchip/rk356x/device.mk:114: vendor.hwc.compose_policy=1 \

这个值是在

/hardware/rockchip/hwcomposer/drmhwc2/rockchip/platform/rk3588/drmvop3588.cpp:2923: int iMode = hwc_get_int_property("vendor.hwc.compose_policy","0");下进行解析的

//force go into GPU
  int iMode = hwc_get_int_property("vendor.hwc.compose_policy","0");

  if((iMode!=1 || gles_policy) && iMode != 2){
    ctx.state.setHwcPolicy.insert(HWC_GLES_POLICY);
    ALOGD_IF(LogLevel(DBG_DEBUG),"Force use GLES compose, iMode=%d, gles_policy=%d, soc_id=%x",iMode,gles_policy,ctx.state.iSocId);
    return 0;
  }

  ALOGD_IF(LogLevel(DBG_DEBUG),"request:afbcd=%d,scale=%d,yuv=%d,rotate=%d,hdr=%d,skip=%d\n"
          "support:afbcd=%d,scale=%d,yuv=%d,rotate=%d,hdr=%d, %s,line=%d,",
