Import many updates from i386's i8259.c, especially genirq transitions.

Shouldn't we try to share i8259.c over the various architectures that
use this controller?  With the generic hardirq framework that should be
possible.

The "i8259" should be under "ISA" or "EISA" Kconfig option.
AFAIK, all known ISA chipsets contains dual i8259 controllers:
LPC on the PCI-ISA bridge (Cobalt, Malta, ...), Intel 82430 EISA Mongoose chipset (Indigo2 IP22, Magnum/Jazz, SNI RM-200, ...)
