[PATCH] kill include/linux/platform.h, default_idle() cleanup

include/linux/platform.h contained nothing that was actually used except
the default_idle() prototype, and is therefore removed by this patch.

This patch does the following with the platform specific default_idle()
functions on different architectures:
- remove the unused function:
  - parisc
  - sparc64
- make the needlessly global function static:
  - arm
  - h8300
  - m68k
  - m68knommu
  - s390
  - v850
  - x86_64
- add a prototype in asm/system.h:
  - cris
  - i386
  - ia64

- * include/linux/platform.h - platform driver definitions

- * Because of the prolific consumerism of the average American,
- * and the dominant marketing budgets of PC OEMs, we have been
- * blessed with frequent updates of the PC architecture. 
- *
- * While most of these calls are singular per architecture, they 
- * require an extra layer of abstraction on the x86 so the right
- * subsystem gets the right call. 
- *
- * Basically, this consolidates the power off and reboot callbacks 
- * into one structure, as well as adding power management hooks.
- *
- * When adding a platform driver, please make sure all callbacks are 
- * filled. There are defaults defined below that do nothing; use those
- * if you do not support that callback.
