[PATCH] iio: adc: rtq6056: Fix the manual device instantiation via sysfs

[cy_huang]

From: Kevin Tung <kevin.tung.openbmc@gmail.com>

Add i2c_device_id to support sysfs manual device instantiation.

Fixes: 89a1034cd841 ("iio: adc: rtq6056: Add support for the whole RTQ6056 family")

Hi, Jonathan:

For some BSP limit, still some user instantiate rtq6056 deivce via sysfs.
Therefore, add old style i2c id to make it compatible for this kind of usage.

BR,
ChiYuan.

Hi,

Please ignore this patch. I have seen Kevin submit the patch in the
