[IA64] sparse cleanup of shub_mmr.h

This patch is a sparse compile cleanup of shub_mmr.h using both the defconfig
and the sn2_defconfig config files.

The issue with this file was the missing usage of __IA64_UL_CONST wrapper.
This wrapper is defined in include/asm-ia64/types.h and wraps a long
constant definition with UL or with nothing depending on its usage in the
kernel.  The missing wrapper caused many sparse compile errors like

        warning: constant 0x0x0000000010000380 so big it is long
