scsi: qla2xxx: edif: Add detection of secure device

Some FC adapters from Marvell offer the ability to encrypt data in flight
(EDIF). This feature requires an application to act as an authenticator.

There is no FC switch scan service that can indicate whether a device is
secure or non-secure.

In order to detect whether the remote port supports encrypted operation,
driver must first do a PLOGI with the remote device. On completion of the
PLOGI, driver will query firmware to see if the device supports secure
login. To do that, driver + firmware must advertise the security bit via
PLOGI's service parameter. The remote device shall respond using the same
service parameter whether it supports it or not.
