The dts property "aspeed,trim-data-valid" is currently used to determine
whether to read trimming data from the OTP register. If this is set on
a device without valid trimming data in the OTP the ADC will not function
correctly. This patch drops the use of this property and instead uses the
default (unprogrammed) OTP value of 0 to detect when a fallback value of
0x8 should be used rather then the value read from the OTP.

Fix channel init for ADC generic channel bindings.
In generic channel initialization, stm32_adc_smpr_init() is called to
initialize channel sampling time. The "st,min-sample-time-ns" property
is an optional property. If it is not defined, stm32_adc_smpr_init() is
currently skipped.
However stm32_adc_smpr_init() must always be called, to force a minimum
sampling time for the internal channels, as the minimum sampling time is
known. Make stm32_adc_smpr_init() call unconditional.

Using this new macro removes the need to mark the callbacks
__maybe_unused. One slightly complexity in this case is that
the export will exist if CONFIG_PM is set, but only be used
if CONFIG_PM_SLEEP is also set. This is harmless.

If CONFIG_PM is not set, the pm_ptr() will ensure that the struct
dev_pm_ops and callbacks are removed without the need for __maybe_unused
markings.
In this case we can't simply use DEFINE_RUNTIME_DEV_PM_OPS() because
that would provide suspend and resume functions without the
checks the driver is doing before calling runtime_pm functions
(whether the necessary GPIO is provided). It may be possible to
clean that up in future by moving the checks into the callbacks.

Add the core driver for the BNO055 IMU from Bosch. This IMU can be
connected via both serial and I2C busses; separate patches will add support
for them.
The driver supports "AMG" (Accelerometer, Magnetometer, Gyroscope) mode,
that provides raw data from the said internal sensors, and a couple of
"fusion" modes (i.e. the IMU also does calculations in order to provide
euler angles, quaternions, linear acceleration and gravity measurements).
In fusion modes the AMG data is still available (with some calibration
refinements done by the IMU), but certain settings such as low pass filters
cut-off frequency and sensors' ranges are fixed, while in AMG mode they can
be customized; this is why AMG mode can still be interesting.

When a IIO device is registered, the IIO core creates an attribute group on
its own, where it puts the channel attributes, and where it copies the
attributes in indio_dev->info->attrs.
Unfortunately it doesn't take care of binary attributes (i.e. it only
consider indio_dev->info->attrs->attrs, and it ignores
indio_dev->info->attrs->bin_attrs).
Fix this by making the IIO layer take care also of the binary attributes.
Note that while it is necessary to copy the non-binary attributes because
the IIO layer needs more room to add the channels attribute, it should be
enough to assign the bin_attrs pointer to the binary attributes pointed by
indio_dev->info->attrs->bin_attrs.
