QCM6125 UEFI XBL显示开机Logo不居中

QCM6125 UEFI XBL显示开机Logo在竖直方向不是居中显示，如果显示屏是正向安装到产品的话可能没有什么问题，但是如果产品的显示屏是90、180、270度旋转后安装到产品上的话显示开机Logo会有一些问题，并且大多数的平台以及产品开机Logo都是水平竖直方向都是居中显示，所以修改成居中显示比较合适

CalculateLogoPosition(

    IN  UINT32                LogoWidth,

    IN  UINT32                LogoHeight,

    OUT UINT32               *pPosX,

    OUT UINT32               *pPosY,

RenderLogoParamsType     *pRenderLogoParams)

      // Calculate LogoPosX and LogoPosY based on platform panel resolution.

      // Center of BGRT image should be at the horizontal center of the panel.

      if (PanelWidth > LogoWidth)

      {

        LogoPosX = ((PanelWidth - LogoWidth)/2);

      }

      // Center of BGRT image should be at 38.2 percent of panel height from the top.

      if (PanelHeight > LogoHeight)

      {

        //luffy modify

        //LogoPosY = (0.382*PanelHeight) - (UINT32)(LogoHeight/2);

        LogoPosY = ((PanelHeight - LogoHeight)/2);

      }

源码中可以看出默认情况是水平方向居中，竖直方向是38.2%位置。

修改为LogoPosY = ((PanelHeight - LogoHeight)/2); 后，竖直方向也可以居中显示
