[PATCH] iio: chemical: atlas-ezo-sensor: Simplify probe()

[PATCH] iio: chemical: atlas-ezo-sensor: Simplify probe()

[Biju Das]

Simplify the probe() by replacing device_get_match_data() and ID lookup
match by i2c_get_match_data() as we have similar I2C and DT-based matching
table.

While at it, drop id variable from probe() as it is unused.

As somebody noticed, this "while at it" part is misleading.
It's integral part of the change.

With that fixed,

Agreed, will drop this and send v2.
