Subject: [PATCH 4.14 71/89] ARM: dts: am335x-boneblack-common: fix memory size

From: Matwey V. Kornilov <matwey@....msu.ru>

[ Upstream commit 5abd45ea0fc3060f7805e131753fdcbafd6c6618 ]

BeagleBone Black series is equipped with 512MB RAM
whereas only 256MB is included from am335x-bone-common.dtsi

This leads to an issue with unusual setups when devicetree
is loaded by GRUB2 directly.
