[PATCH 1/3] Support for PCI Express reset type

[Mike Mason]

This is the first 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 (courtesy of Richard Lary) adds a bit field to pci_dev that indicates whether the device requires a fundamental reset during recovery.

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

Please review and let me know of any concerns.
