Currently, the em_sti driver prepares and enables the needed clock in em_sti_enable(), potentially called through its clockevent device's ->set_state_oneshot().
However, the clk_prepare() step may sleep whereas tick_program_event() and thus, ->set_state_oneshot(), can be called in atomic context.
Split the clk_prepare_enable() in em_sti_enable() into two steps: - prepare the clock at device probing via clk_prepare() - and enable it in em_sti_enable() via clk_enable(). Slightly reorder resource initialization in em_sti_probe() in order to facilitate error handling in later patches.
