[Skiboot] [PATCH] pci: Add -Tn to SAS adapter's loc-code

[Gavin Shan]

This adds -Tn to the device-tree node's loc-code property for SAS
adaptr as we did for ethernet adapter in commit 6558adff01bb ("
Add -Tn to ibm,loc-code for ethernet adaptors"). "n" represents
the function number of the PCI device.
