Subject[PATCH 17/28] ia64: remove the hpsim platform
Date
The hpsim platform supports the HP IA64 simulator which was useful as a
bring up platform. But it is fairly non-standard vs real IA64 system
in that it for example doesn't support ACPI. It also comes with a
whole bunch of simulator specific drivers. Remove it to simplify the
IA64 port.

Note that through a weird twist only them hpsim boot loader built the
vmlinux.gz file, so the makefile targets for that are moved to the
main ia64 Makefile now.
