Subject: [PATCH -mmotm/-next] media: fix timblogiw kconfig & build error

From: Randy Dunlap <randy.dunlap@...cle.com>

timblogiw uses dma() interfaces and it selects TIMB_DMA for that
support.  However, drivers/dma/ is not built unless
CONFIG_DMA_ENGINE is enabled, so select/enable that symbol also.

drivers/built-in.o: In function `timblogiw_close':
timblogiw.c:(.text+0x4419fe): undefined reference to `dma_release_channel'
drivers/built-in.o: In function `buffer_release':
timblogiw.c:(.text+0x441a8d): undefined reference to `dma_sync_wait'
drivers/built-in.o: In function `timblogiw_open':
timblogiw.c:(.text+0x44212b): undefined reference to `__dma_request_channel'
