In the current mainline code, The workaround for i291 is done whenever UART clocks are about to be cut. When the clocks are (re)enabled, the device is put back into no-idle. This patch puts the device into force-idle just before the idle/suspend transistion, but never puts it back into no-idle. So after the first idle/suspend transition, the IP remains in force-idle forever. I don't think that's what we want.
