iio: accel: st_accel_spi: add OF capability to st_accel_spi 

Add device tree support for LIS3DH, LSM330D, LSM330DL, LSM330DLC,
LIS331DLH, LSM330, LSM303AGR, LIS2DH12, LIS3L02DQ, LNG2DM accel sensors.
Fix LIS302DL support defining of_device_id data field in st_accel_of_match
table

Fixes: 762227721f (iio: accel: st_accel: handle deprecated bindings)
