[U-Boot] [PATCH] armv8/fdt: add fixup_crypto_node

[Alex Porosanu]

For Qoriq PPC&ARM v7 platforms, the crypto node is being fixup'ed in order
to update the SEC internal version (aka SEC ERA). This patch adds the
same functionality to the ARMv8 SoCs.

Minor adjustment to commit message format.
Applied to u-boot-fsl-qoriq master, awaiting upstream.

Thanks.
