allmodconfig fails to build with following errors.
drivers/media/platform/sti/bdisp/bdisp-hw.c:
In function 'bdisp_hw_free_nodes':
drivers/media/platform/sti/bdisp/bdisp-hw.c:132:3: error:
implicit declaration of function 'dma_free_attrs'
drivers/media/platform/sti/bdisp/bdisp-hw.c:
In function 'bdisp_hw_alloc_nodes':
drivers/media/platform/sti/bdisp/bdisp-hw.c:157:2: error:
implicit declaration of function 'dma_alloc_attrs'
mn10300 does not provide those functions at this time.
Provide dummy implementations to avoid build errors.
