[PATCH for-next 04/10] IB/hfi1: Remove reading platform configuration from EFI variable

[Dennis Dalessandro <dennis.dalessandro-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

From: Jan Sokolowski <jan.sokolowski-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

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.
