After a build regression report, I took a look at possible users of CONFIG_ISA_DMA_API on m68k and found none, which Greg confirmed. The CONFIG_GENERIC_ISA_DMA option in turn is only needed to implement ISA_DMA_API, and is clearly not used on the platforms with ISA support.
The CONFIG_ISA support for AMIGA_PCMCIA is probably also unneeded, but this is less clear. Unlike other PCMCIA implementations, this one does not use the drivers/pcmcia subsystem at all and just supports the "apne" network driver. When it was first added, one could use ISA drivers on it as well, but this probably broke at some point.
With no reason to keep this, let's just drop the corresponding files and prevent the remaining ISA drivers that use this from getting built.
The remaining definitions in asm/dma.h are used for PCI support.

v2: drop GENERIC_ISA_DMA as well, add some background on CONFIG_ISA.
