MGS-577 ARM: Export the cache management symbols when !MULTI_CACHE
When compiling a GPU module without CONFIG_MULTI_CACHE enabled, the
compiler prompt warning which says symbol v7_dma_map_area and
v7_dma_flush_area not exported. And when insmod GPU module, it also
warns the above two symbols not found, which cause insmod module failed.
This patch export these dma access functions and fix these issues.
