i2c: octeon: thunderx: Limit register access retries
Do not infinitely retry register readq and writeq operations in order to not lock up the CPU in case the TWSI gets stuck. Return -EIO in case of a failed data read. For all other cases just return so subsequent operations will fail and trigger the recovery. Signed-off-by: Jan Glauber <jglauber@cavium.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
