Using the i2c-eg20t driver and call i2cdetect or probe on the bus,
the driver will print a lot of error messages if there was no ACK
received.
i2cdetect normally print a table with all the available devices. If there
is no device on the address, the table will be empty.
Currently with the i2c-eg20t driver, the table is not visible because
the error messages destroy the table.
Error message: pch_i2c_getack return -71
This patch prevent the driver to print the messages to syslog if debug is not set.
Tested on Intel Atom E6xx and Eg20t Chipset.
