This patch is a rewrite of the code to check the PROM version.  The current
code has some deficiences in the way PROM comparisons were made.  The minimum
value of PROM that will boot has also been changed to 4.04.

This patch is a sparse compile cleanup of shub_mmr.h using both the defconfig

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

This patch adds the necessary "hook" to allow SGI/SN
machines to perform a system power off upon a 
'init 0', 'halt -p', 'poweroff' or 'shutdown -h'.

The "hook" is to set the pm_power_off callback
to ia64_sn_power_down(). pm_power_off is checked
in machine_power_off()/do_poweroff() and, if set, is executed. 
ia64_sn_power_down() is a function already present (but not 
used currently) in the sn kernel.
ia64_sn_power_down() makes a SAL call to execute the
power off.
