This set fixes a few errors and gotchas I've found when rebasing my project
on top of 2018-rc4.

First is a breakage with the Linaro compiler -> gcc-linaro-7.2.1 which is a
simple one.

Second is consistency of the __packed attribute - more of a housekeeping
activity.

Last patch fixes a behaviour that has been introduced without I believe
fully thinking through the impact on downstream users.

If we force the DCD to be NULL for olders SoCs - that means people have to
go out and re-sign all of their binaries if they are updating u-boot.

It should be possible to update u-boot in isolation without forcing update
of signed binaries u-boot authenticates via HAB.

If newer NXP SoCs rely on the DCD being NULL then either

1. Just let the authenticate_image() call fail
   It can return an error - this should "just work" if the SoC will
   reject an API callback with the DCD non-NULL then - let it.

2. If the SoC actually has a bug that _requires_ the DCD to be NULL.
   Then add a check into u-boot to check SoC versions.

In either case older SoCs should "just work" and it should be possible to
update u-boot without having to update all associated signed binaries.

Please apply before next official u-boot release.
