[IA64] Kexec: Add kexec_disable_iosapic
Ported from Linux, this shuts down iosapic before preforming kexec.
This resolves a problem whereby the serial port on an HP RX2620
(which uses IOSAPIC) was not able to accept input. It probably
resolves a bunch of other as yet unseen problems too.
Thanks to Takebe-san for working out the solution to this puzzle.
