[RFC: 2.6 patch] DEBUG_KERNEL menu cleanups

[Adrian Bunk <bunk@stusta.de>]

This patch contains the following possible cleanups:
- move DEBUG_FS above the DEBUG_KERNEL options (it did break the menu)
- let the following options depend on DEBUG_KERNEL:
  - PRINTK_TIME
  - DEBUG_SHIRQ
  - RT_MUTEX_TESTER
  - UNWIND_INFO
- fix the formatting of the DEBUG_SHIRQ help text
