ia64: remove the hpsim platform
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.
