MIPS: loongson: remove loongson_dma_supported 
swiotlb_dma_supported will always return true for a mask large enough to
cover the DMA addresses for all physical memory, which is the right
thing to do for swiotlb based dma ops.  This function returned false
if the mask was bigger than a firmware set dma_mask_bits that apparently
can be either 32 or 64, and which seems completely buggys if it actually
is not 64, as the false return negates the whole point of swiotlb.
