crypto: ccree - correct host regs offset
The product signature and HW revision register have different offset on the
older HW revisions.
This fixes the problem of the driver failing sanity check on silicon
despite working on the FPGA emulation systems.
Fixes: 27b3b22dd98c ("crypto: ccree - add support for older HW revs")
