[PATCH v4 02/11] dt-bindings: i2c: Discard i2c-slave flag from the DW I2C example

dtc currently doesn't support I2C_OWN_SLAVE_ADDRESS flag set in the
i2c "reg" property. If it is the compiler will print a warning:

Warning (i2c_bus_reg): /example-2/i2c@1120000/eeprom@64: I2C bus unit address format error, expected "40000064"
Warning (i2c_bus_reg): /example-2/i2c@1120000/eeprom@64:reg: I2C address must be less than 10-bits, got "0x40000064"

In order to silence dtc up let's discard the flag from the DW I2C DT
binding example for now. Just revert this commit when dtc is fixed.

Changelog v3:
- This is a new patch created as a result of the Rob request to remove
the EEPROM-slave bit setting in the DT binndings example until the dtc
is fixed.
