2b4b2bb421 sh: Workaround for __put_user_asm() bug with gcc 4.x on big-endian.
I think this problem is GCC(4.1.2) bug.
Syscall "getdents" returned "dirent->d_off" is always 0.
I think other EB enviroment have same problem.

Problem code
0c03c954 <filldir>:
 :
 c03c97a:       58 f7           mov.l   @(28,r15),r8 !-> offset (high)
 c03c97c:       59 f8           mov.l   @(32,r15),r9 !-> offset (low)
 c03c97e:       53 f9           mov.l   @(36,r15),r3
 c03c980:       54 fa           mov.l   @(40,r15),r4
 :
 c03c9a0:       21 82           mov.l   r8,@r1 !offset(high) -> dirent->d_off

It's workaround patch.

This patch contains the following cleanups:
- make the following needlessly global code static:
  - cf-enabler.c: cf_init()
  - cpu/clock.c: __clk_enable()
  - cpu/clock.c: __clk_disable()
  - process_32.c: default_idle()
  - time_32.c: struct clocksource_sh
  - timers/timer-tmu.c: struct tmu_timer_ops
- remove the following unused functions (no CONFIG_BLK_DEV_FD on sh):
  - process_{32,64}.c: disable_hlt()
  - process_{32,64}.c: enable_hlt()
