Since we are expanding abbrevated register offsets into full macro,
hence these macros should be used in respective read/write
functions(omap1 and omap2plus).
Any other better methods?
generally we always define static inlines for read{b,w,l} and write{b,
w, l}, so instead of calling them omap1_* and omap2_* call them
something like omap_dma_readw(), omap_dma_readl().
