ARM: footbridge: move isa-dma support into footbridge
The dma-isa.c was shared between footbridge and shark a long time ago,
but as shark was removed, it can be made footbridge specific again.
The fb_dma bits in turn are not used at all and can be removed.
All the ISA related files are now built into the platform regardless
of CONFIG_ISA, as they just refer to on-chip devices rather than actual
ISA cards.
