dmaengine: dma-jz4780: Don't depend on MACH_JZ4780

[ Upstream commit c558ecd21c852c97ff98dc6c61f715ba420ec251 ]

If we make this driver depend on MACH_JZ4780, that means it can be
enabled only if we're building a kernel specially crafted for a
JZ4780-based board, while most GNU/Linux distributions will want one
generic MIPS kernel that works on multiple boards.
