ARM: vexpress: Add Device Tree for V2P-CA15_CA7 core tile
This patch adds Device Tree file for the CoreTile Express A15x2 A7x3 (V2P-CA15_CA7). Note that the A7 cpu nodes are commented out, as the big.LITTLE-relevant patches are not upstreamed yet. Till this time one can use the board with two A15 cores only, keeping the A7s in reset by adding the following setting to the board.txt file in Versatile Express configuration tree: SCC: 0x018 0x00001FFF Signed-off-by: Pawel Moll <pawel.moll@arm.com>
