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.
