ALSA: mips: 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_USER as the gfp_t for the memory
allocation, as we should treat this allocation as a normal kernel one.
