crypto: atmel-sha204a - Fix OTP sysfs read and error handling

Fix otp_show() to read and print all 64 bytes of the OTP zone.
Previously, the loop only printed half of the OTP (32 bytes), and
partial output was returned on read errors.

Propagate the actual error from atmel_sha204a_otp_read() instead of
producing partial output.

Replace sprintf() with sysfs_emit_at(), which is preferred for
formatting sysfs output because it provides safer bounds checking.
