    crypto: qat - change value of default idle filter
    
    [ Upstream commit 0f942bdfe9d463be3073301519492f8d53c6b2d5 ]
    
    The power management configuration of 4xxx devices is too aggressive
    and in some conditions the device might be prematurely put to a low
    power state.
    Increase the idle filter value to prevent that.
    In future, this will be set by firmware.
