intel_th: INTEL_TH should depend on HAS_DMA

If NO_DMA=y:

    ERROR: "dma_free_coherent" [drivers/hwtracing/intel_th/intel_th_msu.ko] undefined!
    ERROR: "dma_alloc_coherent" [drivers/hwtracing/intel_th/intel_th_msu.ko] undefined!
    ERROR: "dma_supported" [drivers/hwtracing/intel_th/intel_th.ko] undefined!

Add a dependency on HAS_DMA to fix this.
