i2c: Fix confusing i2c-ibm_iic message

The i2c-ibm_iic driver printed messages in an odd order that seemed
to list devices before the driver was probed.

Here is an example:

at24 0-0052: 512 byte 24c04 EEPROM (writable)
ibm-iic ef600700.i2c: using standard (100 kHz) mode
ad7414 0-004a: chip found

This changes the order to print the i2c driver message before scanning
for devices so that the logs show the driver, then the devices.
