    libpayload: ahci: Fix command engine shutdown
    A timeout while waiting for a device' signature has shown that our
    error path wasn't correct. The shutdown of the ports command engine
    always timed out. Fix that by waiting for FR (FIS Receive Running)
    to be cleared independently from CR (Command List Running) and after
    clearing FRE (FIS Receive Enable).
