-This patch allows passing in the gpio output mask used for GPIO0-7 on the
-PLX PCIe bridge. These GPIO's are used for PERST# on the downstream ports.
-
-Allowing the kernel to override the default configuration allows for keeping
-specific devices held in reset. One important use of this is to allow
-temporarily disabling devices that may request too many resources such as
-an unprogrammed i210 device.
