nvmem: correct Broadcom OTP controller driver writes
- use data write offset to write otp data instead of read offset - use OTP program command 0x8 to write otp with ECC rather than just command 0xA without ECC Fixes: 9d59c6e8ae27 ("nvmem: Add the Broadcom OTP controller driver") Signed-off-by: Oza Pawandeep <oza.oza@broadcom.com> Signed-off-by: Scott Branden <scott.branden@broadcom.com> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
