This makes it possible to work around possible driver or hardware bugs if the feature in question doesn't work as intended for whatever reason.

I couldn't get it to work using the block buffer, so it's using the old-style byte-by-byte mode for now. Note: I'm also updating the driver author... The i2c-i801 driver was really written by Mark Studebaker, even though he based his work on the i2c-piix4 driver which was written by Philip Edelbrock.

I've split the code so that it is more clear which block transaction is performed. First of all the host controller's type is identified. isich4 is set when we think that the controller has the internal buffer. Then, before every block transaction, if isich4 is set, we attempt to enable the E32B bit in SMBAUXCTL register.
