clk: at91: remove IRQ handling and use polling
The AT91 clock drivers make use of IRQs to avoid polling when waiting for some clocks to be enabled. Unfortunately, this leads to a crash when those IRQs are threaded (which happens when using preempt-rt) because they are registered before thread creation is possible. Use polling on those clocks instead to avoid the problem. Acked-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
