[ 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.
