Adding DEVLINK_PERM_CONFIG_SRIOV_ENABLED permanent config
parameter; this parameter controls whether the device
advertises the SR-IOV PCI capability. Value is permanent, so
becomes the new default value for this device.
DEVLINK_PERM_CONFIG_DISABLE = Disable SR-IOV
DEVLINK_PERM_CONFIG_ENABLE = Enable SR-IOV
