[Intel-gfx] errors when building the latest intel DDX driver

[Xiang, Haihao]

Hi, 

  I got the following error message when run 'autogen.sh'

----------------
checking for XORG... configure: error: Package requirements (xorg-server >=  xproto fontsproto  randrproto renderproto xextproto x11 xextproto) were not met:

Requested 'xorg-server >= xproto' but version of xorg-server is 1.10.2.901
----------------

I don't enable SNA, so the required xserver version is 1.6.


This issue is caused by

commit 585667c2f9f88554ed89ff21ae38600f761d964c

    sna: Bump the required xserver version to 1.10


After reverting this commit, I can build DDX driver normally.

Thanks
Haihao
