fix(ti): remove check for zero value in BL31 boot args

The commit 3e14df6f6330 removed clearing of argument registers even when
BL31 is the first stage. In that case the registers are left in a random
state. TI platforms check that the arguments have been zero'd in early
setup and so all TI platforms are not broken. Not sure why this check was
here at all, so simply remove it to fix boot.
