[util] implement flash scrambling key derivation

The address and data flash scrambling keys are computed from seeds
stored in the OTP, and netlist constants embedded in the RTL. This
implements the same flash scrambling key derivation scheme implemented
in the RTL so flash VMEM images can be pre-scrabled for backdoor loading
in DV.
