    drm/xe: Handle unreliable MMIO reads during forcewake
    
    In some cases, when the driver attempts to read an MMIO register,
    the hardware may return 0xFFFFFFFF. The current force wake path
    code treats this as a valid response, as it only checks the BIT.
    However, 0xFFFFFFFF should be considered an invalid value, indicating
    a potential issue. To address this, we should add a log entry to
    highlight this condition and return failure.
    The force wake failure log level is changed from notice to err
    to match the failure return value.
    
    v2 (Matt Brost):
      - set ret value (-EIO) to kick the error to upper layers
    v3 (Rodrigo):
      - add commit message for the log level promotion from notice to err
    v4:
      - update reviewed info
