Add a IIO driver for the Bosch BMA400 3-axes ultra-low power accelerometer.
The driver supports reading from the acceleration and temperature
registers. The driver also supports reading and configuring the output data
rate, oversampling ratio, and scale.

This patch restructures the existing adxl372 driver by adding a module for

commit 762227721f
"iio: accel: st_accel: handle deprecated bindings"
attempted to be smart and let users use the old I2C
driver and the new SPI driver, or the old SPI driver and
the new I2C driver in combination for the LIS3LV02,
and put the restrictions on the I2C and SPI subdrivers
not not be combined with the old subdrivers.
This doesn't work since the IIO ST accel top-level
component selects the I2C and SPI subdrivers, resulting
in the following Kconfig noise:
warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_I2C_3AXIS
which has unmet direct dependencies (IIO && !SENSORS_LIS3_I2C
&& IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_I2C)
warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_SPI_3AXIS
which has unmet direct dependencies (IIO && !SENSORS_LIS3_SPI
&& IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_SPI)
(...)
This fixes the issue by putting the dependencies directly
in the top-level component instead, so that it never gets
to select its unselectable subcomponent.

After this we can start to activate the new driver with the old

Columns shown are x, y, z acceleration, so a positive acceleration
of ~9.81 (shaky due to bad calibration) along the z axis. The
fourth column is the AUX IN which is floating on this system,
it seems to float up to the 2.85V VDD voltage.
