Split serial-isa into its own config option
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).
