[Xf86-video-armsoc] [PATCH] Check for xextproto >= 7.1

[Heiko Stübner]

drmmode_display.c already tries to check if the xext proto is 7.1 or above
to include the correct header, but until now the used constant was not
checked/defined during configure at all.
Add the configure part based on what xf86-video-modesetting does.

I'm not sure what your patch submission expectations are, so
I've picked the three most active devs and the list :-)
