The eg20t driver uses i2c_add_numbered_adapter() to register adapter:

    pch_adap->nr = i;
    ret = i2c_add_numbered_adapter(pch_adap);

Variable i is assigned to 0, it means that i2c_eg20t is the first adapter
by default. if another adapter registers before eg20t, above code return
error for index conflict:

    i2c_eg20t 0000:05:0c.2: pch_i2c_probe :i2c_add_adapter[ch:0] FAILED
    i2c_eg20t: probe of 0000:05:0c.2 failed with error -16

So, we can replace i2c_add_numbered_adapter() with i2c_add_adapter()
interface.since it dynamically allocates the index number.
