[PATCH] ppc32: Fix might_sleep() warning with clock spreading
The clock spreading disable/enable code was called to late/early during the suspend/resume code on some laptops and would trigger a might_sleep() warning due to the down() call in the low level i2c code. This fixes it by calling those functions earlier/later when interrupts are still enabled.
