The ad7292 tries to add an devm_action for disabling a regulator at
device detach using devm_add_action_or_reset(). The
devm_add_action_or_reset() does call the release function should adding
action fail. The driver inspects the value returned by
devm_add_action_or_reset() and manually calls regulator_disable() if
adding the action has failed. This leads to double disable and messes
the enable count for regulator.
Do not manually call disable if devm_add_action_or_reset() fails.

After added inclination angle channels, the trigger buffer size is
insufficient. Extend the buffer size from 16 to 32 bytes, and change
the trigger buffer from the struct to a u8 array to adapt the sensor
with/without inclination angles output.
New trigger buffer data:
- SCA3300: 3 accel channels, temp, and timestamp.
- SCL3300: 3 accel channels, temp, 3 incli channels, and timestamp.
Readjustment the scan index to make it consistent with the buffer data.

iio_format_avail_range() should print range as follow [min, step, max], so
the function was previously calling iio_format_list() with length = 3,
length variable refers to the array size of values not the number of
elements. In case of non IIO_VAL_INT values each element has integer part
and decimal part. With length = 3 this would cause premature end of loop

Letting the compiler remove these functions when the kernel is built
without CONFIG_PM support is simpler and less error prone than the
use of #ifdef based config guards.
Removing instances of this approach from IIO also stops them being
copied into new drivers.
Very likely it would be safe to use DEFINE_RUNTIME_DEV_PM_OPS() here,
but that would be a functional change.
