mpc5200: digsy_mtc: Fix extension board detection
Switch to extension board detection using pci_find_device() instead of detecting by i2c access to EEPROM device on extension board. This is a cleaner detection method since EEPROM addresses can be different on different board revisions. This also avoids "i2c_read: failed to address chip" error messages in the boot log on boards without extension board which may confuse users. Signed-off-by: Anatolij Gustschin <agust@denx.de>
