This patch restructures the existing adxl372 driver by adding a module for
SPI and a header file, while the baseline module deals with the chip-logic.
This is a necessary step, as this driver should support in the future
a similar device which differs only in the type of interface used (I2C
instead of SPI).

The ADXL375 is fully register map compatible to the ADXL345 (including the
device ID register returning the same value ...).
The only difference is the resolution of the acceleration sensor. The
ADXL375 can measure up to +-200g of acceleration.

Add driver to support older EC firmware that only support deprecated

information.
Present same interface as the regular cros_ec sensor stack:
- one iio device per accelerometer
- use HTML5 axis definition
- use iio abi units
- accept calibration calls, but do nothing

commit 762227721fe6225be5b6d233ef681aea5871f5f3
"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.

The earlier deployed LIS3LV02DL driver had already defined a few
DT bindings that need to be supported by the new more generic
driver and listed as compatible but deprecated bindings in the
documentation.
After this we can start to activate the new driver with the old
systems where applicable.
As part of this enablement: make us depend on the old drivers
not being in use so we don't get a kernel with two competing
drivers.

As is custom with all modern sensors, add a clever burst mode
that will just stream out values from the sensor and provide it
to userspace to do the proper offsetting and scaling.
This is the result when tested with an HRTimer trigger:

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.
To be able to cleanup the triggered buffer, we need to add .remove()
callbacks to the I2C and SPI subdrivers and call back into an
exported .remove() callback in the core.

This moves the KXSD9 SPI transport out to its own file and Kconfig
entry, so that we will be able to add another transport method.
We export the common probe and add a local header file for the
functionality shared between the main driver and the transport
driver.
We make the SPI transport the default for the driver if SPI is
available and the KXSD9 driver was selected, so the oldconfig
upgrade path will be clear.

Jonathan writes:
First set of IIO fixes for the 4.5 cycle.
This set comprises those not dependent on patches in the 4.5 merge cycle.
A second set will follow shortly with ones that are.
* core in kernel interfaces
- fix a possible NULL dereference that is a theoretical possibility
via odd usage of iio_channel_release. Pretty much a hardening of
the interface, but observed in the wild with the twl4030_charger
driver.
* acpi-als
- report the data as processed as it is in lux. This fixes a wrong
use of the IIO ABI. However, old _raw version retained to avoid
breaking any userspace in the wild that is relying on that (none
known but it doesn't hurt us much to retain it)
* ade7753
- fix some error handling to avoid use of unitialized data.
* ltr501
- use a signed return type for ltr501_match_samp_freq so as to allow
returning of an error code.
* mcp4725
- set name field of struct iio_dev to ensure the sysfs name attribute
doesn't give NULL.
* mpl115
- temperature offset sign is wrong.
* stk8ba50
- IIO_TRIGGER dependency added
* ti_am335x_adc
- Label buffer as a software buffer. It's actually a hybrid of a
true hardware buffer feeding a kfifo, but the meaning of these fields
has changed a little recently and in this case it should be labeled
a software buffer ensure it is allowed to use the kfifo.
* vf610_adc
- HAS_IOMEM dependency
