The errata handling for i291 is moved from device code to driver code but it's functionality is also changed (but not described.) 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.
