  Fix parsing of I2C addresses properties in fdt data.  I2C address is
  represented in 7-bits format in DT files, but system expect it in 8-bit
  format.  Also, fix two drivers that locally hack around this bug.

  This includes a direct-commit change to the beaglebone dts data in the
  10-stable branch to adjust the i2c slave addresses directly.  In -current
  the equivelent change happened with a switch from homegrown to standard
  fdt data.
