MIPS: lantiq: pass struct device to DMA API functions
The DMA API generally relies on a struct device to work properly, and
only barely works without one for legacy reasons.  Pass the easily
available struct device from the platform_device to remedy this.

Also use GFP_KERNEL instead of GFP_ATOMIC as the gfp_t for the memory
allocation, as we aren't in interrupt context or under a lock.

Note that this whole function looks somewhat bogus given that we never
even look at the returned dma address, and the CPHYSADDR magic on
a returned noncached mapping looks "interesting".  But I'll leave
that to people more familiar with the code to sort out.
