The real SuperI/O chips emulated by QEMU allow for relocating and enabling or
disabling their SuperI/O functions via software. So far this is not implemented.
Prepare for that by adding isa_fdc_set_{enabled,iobase}.

FDCtrl::portio_list isn't used inside FDCtrl context but only inside
FDCtrlISABus context, so move it there.

isa_get_dma() returns a DMA channel handler from an ISABus.
To emphasize this, rename it as isa_bus_get_dma().
Mechanical change using:
$ sed -i -e 's/isa_get_dma/isa_bus_get_dma/g' \
$(git grep -l isa_get_dma)

isa_init_irq() has become a trivial one-line wrapper for isa_get_irq().
It can therefore be removed.

Other ISA devices such as serial-isa use the properties in their
build_aml functions. fdc-isa not using them is probably an oversight.

Some machines use floppy controllers via the SysBus interface,
and don't need to pull in all the ISA code.
Extract the ISA specific code to a new unit: fdc-isa.c, and
add a new Kconfig symbol: "FDC_ISA".
This allows us to remove the FIXME from commit dd0ff8191a
("isa: express SuperIO dependencies with Kconfig").
