Documentation/process/license-rules.rst and checkpatch expect the SPDX
identifier syntax for multiple licenses to use capital "OR". Correct it
to keep consistent format and avoid copy-paste issues.

Replace the EFI runtime services check with one that tells us whether
EFI GetVariable() is implemented by the firmware.

The EFI variable that provides board ID is named
by the PCI address of the device, which is published
in upper-case, while the HFI1 driver reads the EFI
variable in lower-case.
This prevents returning the correct board id when
queried through sysfs. Read EFI variables in
upper-case if the lower-case read fails.

The TODO list for the hfi1 driver was completed during 4.6. In addition
other objections raised (which are far beyond what was in the TODO list)
have been addressed as well. It is now time to remove the driver from
staging and into the drivers/infiniband sub-tree.
