selfboot: Move the usable-RAM check into a function
In preparation for making this check optional, move it into its own
function. load_self_segments() is already long and we don't want to make
it longer.
BUG=chrome-os-partner:56314
BRANCH=none
TEST=boot on gru and see that BL31 loads and runs correctly
