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/VX800/VX820 additionally appears to support SMBus PEC, although
this driver doesn't implement it yet.
