Add system sleep power management support to st_lsm6dsx driver.
In particular during suspend phase each sensor is disabled and
hw fifo is configured in bypass in order to avoid subsequent
I/O operations. The patch has been tested on HiKey board device

This patch allows to avoid a transitory that occurs when a given sensor
has been already enabled (e.g. gyroscope) and the user is configuring
the sample frequency of the other one (e.g. accelerometer).
The transitory lasts until the accelerometer is enabled.
During that time slice the gyroscope ODR is incorrectly modified as well.
At the end of the transitory both sensors work at the right frequency.
Fix it introducing st_lsm6dsx_check_odr() routine to check ODR consistency
in write_raw handler in order to apply frequency configuration just
in st_lsm6dsx_set_odr()
