[ARM] 4818/1: RealView: Add core-tile detection
This patch adds the core-tile detection and only enables devices if the corresponding tile is present. It currently detects the ARM11MPCore via the core_tile_eb11mp() macro. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
