I2C: JZ4780: Fix bug for Ingenic X1000.

Browse source

Only send "X1000_I2C_DC_STOP" when last byte, or it will cause
error when I2C write operation which should look like this:

device_addr + w, reg_addr, data;

But without this patch, it looks like this:

device_addr + w, reg_addr, device_addr + w, data;
