[PATCH] iio: imu: inv_icm45600: Use I2C match data

[Pengpeng Hou]

The I2C driver provides chip_info through both the OF match table and
the I2C id table, but probe reads it with device_get_match_data().  That
misses id-table driver_data for non-firmware I2C matches and can reject
a supported device with -ENODEV.

Use i2c_get_match_data() so the id-table chip_info is used when firmware
match data is not present.

Currently there is no problem with that. But in principle I agree with
the change. Also it makes it on par with SPI glue driver.
