gpio: pca9570: Use I2C match data

Browse source

The driver stores chip metadata in both the OF match table and the I2C
id table, but probe currently reads it with device_get_match_data().
That helper only returns firmware-node match data, so an I2C-id/modalias
match can leave chip_data NULL before the driver dereferences it to read
ngpio.

Use i2c_get_match_data() so the I2C id table driver_data is consumed
when firmware match data is not present.
