[PATCH 24/32] clocksource+irqchip: delete __cpuinit usage from all related files

[Paul Gortmaker <paul.gortmaker@windriver.com>]

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

This removes all the drivers/clocksource and drivers/irqchip uses of
the __cpuinit macros from all C files.

[This commit is part of the __cpuinit removal work.  If you don't see
 any problems with it, then you don't have to do anything ; it will be
 submitted with all the rest of the __cpuinit removal work.  On the
 other hand, if you want to carry this patch in with your other pending
 changes so as to handle conflicts with other pending work yourself, then
 that is fine too, as the commits can largely be treated independently.
 For more information, please see: https://lkml.org/lkml/2013/6/20/513 ]
