[PATCH v2 05/12] i2c: nomadik: change print level for fault messages to debug

[Dmitry Guzman <Dmitry.Guzman@mobileye.com>]

i2c-nomadik driver prints error message on every faulted message. This
is not a good practice, because in I2C a fault not always is an error,
sometimes it is the expected result. For example, scanning bus with
`i2cdetects` prints over 100 messages in dmesg (two messages per each
target address).

To avoid excessive prints in the log, change the print level from err to
debug.
