ARM: dts: am335x-boneblack-common: fix memory size

BugLink: https://bugs.launchpad.net/bugs/1864904
[ 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.
