Subject: [PATCH 3/4] i915: add -DDYNAMIC_DEBUG_MODULE to i915/gvt/Makefile

This addition to cflags enables dyndbg in the gvt component of the
i915 module, on a CONFIG_DYNAMIC_DEBUG_CORE build.

So here are the message classifications that the gvt driver uses.

   cut -d= -f2 | cut -d\  -f2,3 | \
   perl -ne 'chomp $_ && $h{$_}++; END{print "$_\" \tseen $h{$_}\n" for sort keys %h}'

"gvt: cmd:" 	seen 11
"gvt: core:" 	seen 48
"gvt: dpy:" 	seen 4
"gvt: el:" 	seen 21
"gvt: irq:" 	seen 1
"gvt: mm:" 	seen 6
"gvt: mmio:" 	seen 9
"gvt: render:" 	seen 1
"gvt: sched:" 	seen 15
