[PATCH v2 27/38] fbdev/sh7760fb: Alloc DMA memory from hardware device

Pass the hardware device to the DMA helpers dma_alloc_coherent() and dma_free_coherent(). The fbdev device that is currently being used is a software device and does not provide DMA memory. Also update the related dev_*() output statements similarly.
