Subject: scsi: lpfc: Add 64G link speed support
Patch-mainline: v4.17-rc1
Git-commit: fbd8a6ba65443a8a79183edd9c2e1ad302339063
References: bsc#1082595
The G7 adapter supports 64G link speeds. Add support to the driver.
In addition, a small cleanup to replace the odd bitmap logic with
a switch case.
