renesas: support for RCar-3 D3 DRAAK

meta-renesas has support for the D3 Draak board only in version
Renesas-Yocto-v2.22.0.1_D3 version. Other Renesas boards are already
using more recent verions. Checkout the D3 specific version
in a different directory, so that all Reneasas boards can be supported.
renesas-rcar-gen3 repo has been updated with D3 drivers from
D3_Linux_2.23.01_BSP_3D BSP package.

+From: Linus Torvalds <torvalds@linux-foundation.org>
+Date: Thu, 2 Mar 2017 12:17:22 -0800
+Subject: [PATCH] give up on gcc ilog2() constant optimizations
+
+gcc-7 has an "optimization" pass that completely screws up, and
+generates the code expansion for the (impossible) case of calling
+ilog2() with a zero constant, even when the code gcc compiles does not
+actually have a zero constant.
+
+And we try to generate a compile-time error for anybody doing ilog2() on
+a constant where that doesn't make sense (be it zero or negative).  So
+now gcc7 will fail the build due to our sanity checking, because it
+created that constant-zero case that didn't actually exist in the source
+code.
+
+There's a whole long discussion on the kernel mailing about how to work
+around this gcc bug.  The gcc people themselevs have discussed their
+"feature" in
+
+   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=72785
+
+but it's all water under the bridge, because while it looked at one
+point like it would be solved by the time gcc7 was released, that was
+not to be.
+
+So now we have to deal with this compiler braindamage.
+
+And the only simple approach seems to be to just delete the code that
+tries to warn about bad uses of ilog2().
+
+So now "ilog2()" will just return 0 not just for the value 1, but for
+any non-positive value too.
+
+It's not like I can recall anybody having ever actually tried to use
+this function on any invalid value, but maybe the sanity check just
+meant that such code never made it out in public.
