[IA64] workaround tiger ia64_sal_get_physical_id_info hang

This fixes regression introduced in 113134fcbca83619be4c68d0ca66db6093777b5d

Intel Tiger platforms hang when calling SAL_GET_PHYSICAL_ID_INFO
instead of properly returning -1 for unimplemented, so add a
version check.

SGI Altix platforms have an incorrect SAL version hard-coded into
their prom -- they encode 2.9, but actually implement 3.2 -- so
fix it up and allow ia64_sal_get_physical_id_info to keep
working.
