Currently, the code to handle the legacy ISA bus is always included in
qemu. However there are lots of platforms that don't include ISA legacy
devies, and quite a few that have never used ISA legacy devices at all.
This patch allows the ISA bus code to be disabled in the configuration for
platforms where it doesn't make sense.
For now, the default configs are adjusted to include ISA on all platforms
including PCI: anything with PCI can at least in principle add an i82378
PCI->ISA bridge. Also, CONFIG_IDE_CORE which is already in pci.mak
requires ISA support.
We also explicitly enable ISA on some other non-PCI platforms which include
ISA devices: moxie, sparc and unicore32. We may want to pare this down in
future.
The platforms that will lose ISA by default are: cris, lm32, microblazeel,
microblaze, openrisc, s390x, tricore, xtensaeb, xtensa. As far as I can
tell none of these ever used ISA.

At present, the core device model code for 8250-like serial ports
(serial.c) and the code for serial ports attached to ISA-style legacy IO
(serial-isa.c) are both controlled by the CONFIG_SERIAL variable.
There are lots and lots of embedded platforms that have 8250-like serial
ports but have never had anything resembling ISA legacy IO. Therefore,
split serial-isa into its own CONFIG_SERIAL_ISA option so it can be
disabled for platforms where it's not appropriate.
For now, I enabled CONFIG_SERIAL_ISA in every default-config where
CONFIG_SERIAL is enabled, excepting microblaze, or32, and xtensa. As best
as I can tell, those platforms never used legacy ISA, and also don't
include PCI support (which would allow connection of a PCI->ISA bridge
and/or a southbridge including legacy ISA serial ports).
