Subject: IB/hfi1: Remove reading platform configuration from EFI variable
Patch-mainline: v4.14-rc1
Git-commit: f5114440c5491d4737b061c3a77195088bbaca52
References: bsc#1060463 FATE#323043

Currently, platform configuration can be read from EFI variable
for discrete cards. It will happen when reading from EPROM fails.
EFI variables should not be queried for platform configuration
in any scenario.
