m68k/atari - ataflop: use correct virt/phys translation for DMA buffer

Browse Source 
With the kernel running from FastRAM instead of ST-RAM, none of ST-RAM is
mapped by mem_init, and DMA-addressable buffer must be mapped by ioremap.

Use platform specific virt/phys translation helpers for this case.
