[PATCH u-boot-mvebu v2 19/41] tools: kwbimage: Do not hide usage of secure header under CONFIG_ARMADA_38X

[Marek Behún]

From: Pali Rohár <pali at kernel.org>

The mkimage host tool can be used to generate kwbimage v1 image with
secure header on host system for A38x plaform also when U-Boot is being
compiled for different platform. So there is no reason to not allow
compiling of mkimage/kwbimage with secure header support for e.g. x86-64
host.
