[IA64] refresh arch/ia64/defconfig

Refresh arch/ia64/defconfig, as it was getting a bit stale.  The only
manual changes I made were:

CONFIG_SCSI_SATA=y		needed for some Altix base I/O cards
CONFIG_SCSI_SATA_VITESSE=y

CONFIG_DM_MULTIPATH=m		the rest are already modules

CONFIG_FUSION_SPI=y		new driver breakout
CONFIG_FUSION_FC=m

CONFIG_SGI_TIOCX=y		enable some other SGI drivers
CONFIG_SGI_MBCS=m
CONFIG_AGP_SGI_TIOCA=m

Boot tested on Altix, HP rx2600 and Intel Tiger
