    i2c-viapro: Add support for the VIA CX700 south bridge
    
    We do not have any documentation for the CX700, but it was reported
    to work fine. Thanks to Claas Langbehn for testing.

 Except for the oldest chips (VT82C596A/B, VT82C686A and most probably
 VT8231), this driver supports I2C block transactions. Such transactions
 are mainly useful to read from and write to EEPROMs.

+The CX700 additionally appears to support SMBus PEC, although this driver
+doesn't implement it yet.
