iio: imu: st_lsm6dsx: discard samples during filters settling time
During digital filters settling time the driver is expected to drop
samples since they can be corrupted. Introduce the capability to drop
a given number of samples according to the configured ODR.
Add sample_to_discard for LSM6DSM-like sensors since new generation
devices (e.g. LSM6DSO) support DRDY mask where corrupted samples are
masked in hw with values greather than 0x7ffd so the driver can easily
discard them.
I have not added sample_to_discard support for LSM6DS3 or LSM6DS3H since
I do not have any sample for testing at the moment.

iio: core: Simplify the registration of kfifo buffers
Among all the users of the kfifo buffers, no one uses the
INDIO_BUFFER_HARDWARE mode. So let's take this as a general rule and
simplify a little bit the internals - overall the documentation - by
eliminating unused specific cases. Use the INDIO_BUFFER_SOFTWARE mode by
default with kfifo buffers, which will basically mimic what all the "non
direct" modes do.

iio: make use of devm_iio_kfifo_buffer_setup() helper
All drivers that already call devm_iio_kfifo_allocate() &
iio_device_attach_buffer() are simple to convert to
iio_device_attach_kfifo_buffer() in a single go.
This change does that; the unwind order is preserved.
What is important, is that the devm_iio_kfifo_buffer_setup() be called
after the indio_dev->modes is assigned, to make sure that
INDIO_BUFFER_SOFTWARE flag is set and not overridden by the assignment to
indio_dev->modes.
Also, the INDIO_BUFFER_SOFTWARE has been removed from the assignments of
'indio_dev->modes' because it is set by devm_iio_kfifo_buffer_setup().

iio:imu:st_lsm6dsx Fix alignment and data leak issues
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to an array of suitable structures in the iio_priv() data.
This data is allocated with kzalloc so no data can leak apart from
previous readings.
For the tagged path the data is aligned by using __aligned(8) for
the buffer on the stack.
There has been a lot of churn in this driver, so likely backports
may be needed for stable.

iio: imu: st_lsm6dsx: fix decimation factor estimation
Fix decimation factor and sip estimation for LSM6DSM series
(max value for decimation factor is 32).
If gyro and accel sensors are enabled at 12.5Hz and 416Hz
respectively, decimation factor lookup will fail, producing
unaligned data.
Remove unused decimator filed in st_lsm6dsx_sensor structure.

iio: imu: st_lsm6dsx: add odr calibration feature

iio: imu: st_lsm6dsx: add odr calibration feature
On LSM6DSO/LSM6DSR/LSM6DSOX/ASM330LHH and ISH330DHCX
devices it is possible to trim the hardware timestamp
resolution through the FREQ_FINE[7:0] bits of the
INTERNAL_FREQ_FINE register, which contains the difference
in percentage of the effective ODR (and timestamp rate)
with respect to the typical value.
The formula for calculating the effective ODR reported
in the application notes has been linearized to the first
order to simplify the calculation (pls. see note on source
code).
This change may be useful in the outcome of CTS
tests regarding the SingleSensorTests and the
SensorTest#testSensorTimeStamps for high ODRs
