Add the HOLD field management. Some i2c devices need a longer data hold
time than the one given in the i2c bus specification. Since this value
depends on the i2c device connected to the bus, add a DT property to
configure it: "atmel,twd-hold-cycles".

We already have "i2c-sda-hold-time-ns". Can you use that one? Sorry that
this is not obviously documented, I am working on it...
