hwrng: Pass entropy to add_hwgenerator_randomness() in bits, not bytes

Browse source 
rng_get_data() returns the number of bytes read from the hardware.
The entropy argument to add_hwgenerator_randomness() is passed
directly to credit_entropy_bits() so we should be passing the
number of bits, not bytes here.
