[PATCH 3/3] Support for PCI Express reset type

This is the third of three patches that implement a bit field that PCI Express device drivers can use to indicate they need a fundamental reset during error recovery.

By default, the EEH framework on powerpc does what's known as a "hot reset" during recovery of a PCI Express device.  We've found a case where the device needs a "fundamental reset" to recover properly.  The current PCI error recovery and EEH frameworks do not support this distinction.

The attached patch makes changes to EEH to utilize the new bit field.

These patches supersede the previously submitted patch that implemented a fundamental reset bit field.

Please review and let me know of any concerns.
