[PATCH 6/7] efi: Handle secure boot from UEFI-2.6 [ver #7]

So this patch should take AuditMode into account, but not DeployedMode, i.e.,

SecureBoot == 0x1
SetupMode == 0x0
AuditMode == 0x0 (or non-existent)

If we're in audit mode or setup mode SecureBoot==0 and SetupMode==1 according
to the flowchart, so the check of AuditMode would seem redundant.

Further, the checks above don't seem to differentiate deployed mode from user
mode.  Should they?
