refactor(measured_boot): remove passing of BL2 hash via device tree

Subsequent patches will provide a solution to do the BL2 hash measurement
and recording in BL1 itself, hence in preparation to adopt that solution
remove the logic of passing BL2 hash measurement to BL2 component
via TB_FW config.
