For today the st_lsm6dsx driver support LSM6DSO and LSM6DSR sensor only in
spi and i2c mode.
The LSM6DSO and LSM6DSR are also i3c capable so lets give i3c support to
them.

The i3c bus spec defines a bus configuration where i2c devices don't
have a 50ns filter but support SCL running at SDR max rate (12.5MHz).
This patch introduces the limited bus mode so that users can use
a higher speed in presence of i2c devices index 1.

For today the st_lsm6dsx driver support lsm6dso sensor only in
spi and i2c mode.
The lsm6dso is also i3c capable so lets give i3c support to it.

The i3c bus spec define a bus configuration where the i2c devices
doesn't have the 50ns filter yet they allow the SDR max speed.
This patch introduce the limited bus mode so the users can use
a higher speed on presence of i2c devices index 1.
