ARM: 6186/1: Avoid the CONSISTENT_DMA_SIZE warning on noMMU builds
This macro is not defined when !CONFIG_MMU so this patch moves the CONSISTENT_* definitions to the CONFIG_MMU section. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
