hw/misc/aspeed_hace: Extract non-accumulation hash execution into helper function

To improve code readability and maintainability of do_hash_operation(), this
commit introduces a new helper function: hash_execute_non_acc_mode().

The helper encapsulate the hashing logic for non-accumulation mode.

No functional changes are introduced.
