c9c1d6d820 iio: imu: st_lsm6dsx: fix build when CONFIG_IIO_TRIGGERED_BUFFER=m 
The following kernel linkage error:

st_lsm6dsx_core.o: in function `st_lsm6dsx_sw_buffers_setup':
st_lsm6dsx_core.c:2578: undefined reference to `devm_iio_triggered_buffer_setup_ext'

is caused by the fact that the object owning devm_iio_triggered_buffer_setup_ext()
(drivers/iio/buffer/industrialio-triggered-buffer.o) is allowed to be
built as module when its user (drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_core.c)
is built-in.

The st_lsm6dsx driver already has a "select IIO_BUFFER", so add another
select for IIO_TRIGGERED_BUFFER, to make that option follow what is set
for the st_lsm6dsx driver. This is similar to what other iio drivers do.

52f4b1f196 iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1 
The LSM9DS1's accelerometer / gyroscope unit and it's magnetometer (separately
supported in iio/magnetometer/st_magn*) are located on a separate i2c addresses
on the bus.

For the datasheet, see https://www.st.com/resource/en/datasheet/lsm9ds1.pdf

Treat it just like the LSM6* devices and, despite it's name, hook it up
to the st_lsm6dsx driver, using it's basic functionality.

accelerometer and gyroscope are not independently clocked. It runs at the gyro
frequencies if both are enabled, see chapter 7.12 of the datasheet.
We could have handled this as a single IIO device but we have split
it up to be more consistent with the other more flexible devices.

Despite supporting and testing the LSM9DS1, we call the gyro channels
iio_chan_spec struct "st_lsm6ds0_gyro_channels" because the register
description is equal. This suggests that supporting LSM6DS0 should be
trivial to do.

For today the st_lsm6dsx driver support LSM6DSO and LSM6DSR sensor only in

The LSM6DSO and LSM6DSR are also i3c capable so let's give i3c support to
them.

(32 / SAMPLE_SIZE) * SAMPLE_SIZE since spi_write_then_read() used in

avoid a kmalloc for each bus access.
