arch/arm64: Override bl31 timestamp with coreboot build timestamp
If coreboot's build process is reproducible (eg. using the latest git
timestamp as source), bl31 is, too.
This requires an arm-trusted-firmware side merge first (in progress) and
an update of our reference commit for the submodule, but it also doesn't
hurt anything because it merely sets a variable that currently goes
unused.
