rcar-gen3: xserver-xorg: Downgrade to use 1.19.6 version

In YP2.8, xserver-xorg was upgraded to 1.20.4.
This breaks xserver-xorg congigures:

| configure: error: Package requirements (libdrm >= 2.4.89) were not met:
| Requested 'libdrm >= 2.4.89' but version of libdrm is 2.4.85

However, Renesas BSP uses libdrm version is 2.4.85.
Therefore, let downgrade this version to use 1.19.6.

+Subject: [PATCH] modesetting: Fix 16 bit depth/bpp mode
+
+When setting DefaultDepth to 16 in the Screen section, the current
+code requests a 32 bpp framebuffer, however the X-Server seems to
+assumes 16 bpp.
+
+Fixes commit 21217d02168d ("modesetting: Implement 32->24 bpp
+conversion in shadow update")
