        sys/dev/i2c/spdmem_i2c.c: revision 1.14

Use 1-byte data-buffers when writing to the "control" device for the
SPD ROMs (we do this for page-selection).  The imcsmb doesn't support
zero-byte transfers.

With this, I'm able to get the data for all 8 of my DIMMs (on two
different imcsmb busses) using the spdmem(4) driver.  And the data
decodes correctly using the decode-dimms utility (from the linux
i2ctools).
