armtf: hikey_ddr: Add NOTICE message to avoid boot hang (racy!)
So for some reason, when building with the android toolchain,
the hikey ddr initialization code gets stuck.
Adding a NOTICE message here avoids it, which basically tells me
something is broken (possibly the toolchain reordering operations,
or some other memory barrier type issue).
But here we are.
