Subject: IB/hfi1: Remove HFI1_VERBS_31BIT_PSN option
Patch-mainline: v4.14-rc1
Git-commit: 6165467921a891bc79675cdb7f2791d8331f592c
References: bsc#1060463 FATE#323043

Remove HFI1_VERBS_31BIT_PSN Kconfig option leaving only 31-bit PSNs
available. The option was implemented in the early days of the driver
and is no longer needed.
