iio: imu: inv_icm42600: Fix broken icm42600 (chip id 0 value)

commit 106b391e1b859100a3f38f0ad874236e9be06bde upstream.

The 0 value used for INV_CHIP_ICM42600 was not working since the
match in i2c/spi was checking against NULL value.

To keep this check, add a first INV_CHIP_INVALID 0 value as safe
guard.
