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

2017-02-19IB/hfi1: Check upper-case EFI variablesSebastian Sanchez
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.

2016-05-26IB/hfi1: Move driver out of stagingDennis Dalessandro
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.
