[PATCH v2 4/6] iio: accel: adis16201: add ADIS16203 support

Add ADIS16203 from staging to mainline ADIS16201. ADIS16203 shares same SPI protocol and register addresses. Differing parameters are handled by adis16201_chip_info structure. ADIS16203 specific support includes DIAG_STAT_SELFTEST_FAIL_BIT, which is supported only on ADIS16203, and a separate channel array. Kconfig is updated accordingly.
