Subject: [PATCH v2] dts: add specific compatible type for Terasic DE0-NANO-SoC  Board

From: Tim Sander <tim@...eglstein.org>

Add a more specific compatible string:"terasic,de0-nano-soc" for respective board.
Background: when checking for bootspec entries, some board specific fixups are
not apropriate for board of the same platform ("altr,socfpga-cyclone5").
The same aproach is taken with the EBV-Socrates board.
