meta-yocto-bsp: workaround the X malfunction on beaglebone
After the change in kernel commit a291b6b3d287 ("ARM: dts: am335x-boneblack: Add blue-and-red-wiring -property to LCDC node"), the pixel format we support for 32bit bpp has been changed from XRGB8888 to XBGR8888. But the fbdev created by modesetting driver use the XRGB8888 format by default, this causes the X malfunction. There is no easy way to adjust the pixel format of the fbdev created by the modesetting driver. So we create a xorg.conf to use the 16bit bpp to work around this issue.
