Details:
When configured as the master, the I2C module does not allow 0-byte data

undefined behavior.
Workaround(s):
No workaround. Do not use 0-byte data requests.
The writes in question are unnecessary from a functional point of view.
Most of them are done after I/O has finished, and the only one that preceds
I/O (in i2c_probe()) is also unnecessary because a stop bit is sent before
actual data transmission takes place.
Therefore, remove all writes that zero the cnt register.

cmd_eeprom: bug fix for i2c read/write
The local pointer of address (i.e., addr) only gets
referenced under SPI mode, and it won't be appropriate
to pass only 1-byte addr[1] to i2c_read/i2c_write while
CONFIG_SYS_I2C_EEPROM_ADDR_LEN > 1.
1. In U-boot's I2C model, the address would be re-assembled
to a byte string in MSB order inside I2C controller drivers.
2. The 'CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW' option which could
be found at soft_i2c.c is always turned on in cmd_eeprom.c,
the addr[0] always contains the device address with overflowed
MSB address bits.
