[PATCHv6 01/11] ARM: OMAP: clockdomain: Fix locking on _clkdm_clk_hwmod_enable / disable

Previously the code only acquired spinlock after increasing / decreasing
the usecount value, which is wrong. This leaves a small window where
a task switch may occur between the check of the usecount and the actual
wakeup / sleep of the domain. Fixed by moving the spinlock locking before
the usecount access. Left the usecount as atomic_t if someone wants an
easy access to the parameter through atomic_read.

Thanks, queued for 3.7-rc fixes.
