iio: imu: inv_icm42600: Fix broken icm42600 (chip id 0 value)
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.
Fixes: 31c24c1e93c3 ("iio: imu: inv_icm42600: add core of new inv_icm42600 driver")
