armv8/fdt: add fixup_crypto_node
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. Signed-off-by: Alex Porosanu <alexandru.porosanu@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
