kernel: backport RTL8366RB patches
These upstream patches makes the RTL8366RB DSA switch work properly with OpenWrt, the D-Link DIR-685 gets network and can be used as a router, and the same should be applicable for any other device that want to enable the RTL8366RB through Device Tree.

+Subject: [PATCH 1/5] net: dsa: rtl8366: Pass GENMASK() signed bits
+
+Oddly, GENMASK() requires signed bit numbers, so that it can compare
+them for < 0. If passed an unsigned type, we get warnings about the
+test never being true.
