mmtimer: Remove the SGI SN2 mmtimer driver
This driver supports direct system clock access on the ancient SGI SN2 IA64 systems, and implement the only non-builtin k_clock instance. Remove it as any remaining IA64 altix user will be running just as old distros anyway. Dimitri Sivanich stated: "Since this is SN2 specific, this can be removed." Note that this does not affect the never uv_mmtimer driver for x86-based Altix systems.
