[U-Boot] [PATCH 1/6] riscv: clarify error message on undefined exceptions

Undefined exceptions are treated as reserved. This is not clearly
communicated to the user. Adjust the error message to clarify that a
reserved exception has occurred and add additional details.

Fixes: e8b522b ("riscv: treat undefined exception codes as reserved")
