hwrng: octeon - Use devm_hwrng_register
Use resource managed function devm_hwrng_register instead of hwrng_register to make the error-path simpler. Also, remove octeon_rng_remove as it is now redundant. Signed-off-by: Vaishali Thakkar <vthakkar1994@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
