This patch removes the macro IIO_DEV_ATTR_CH_OFF. The macro
IIO_DEV_ATTR_CH_OFF is not required, due to the replace of it by the
direct use of IIO_DEVICE_ATTR in files staging/iio/meter/ade7759.c and
staging/iio/meter/ade7753.c.

The macro IIO_DEV_ATTR_CH_OFF is a wrapper for IIO_DEVICE_ATTR, with a
tiny change in the name definition. This extra macro does not improve
the readability and also creates some checkpatch errors.

This patch fixes the checkpatch.pl errors:

The function magn_3d_read_raw has a switch statement handling multiple
cases per channel. The first case statement uses the magic number 0,
which means IIO_CHAN_INFO_RAW. Additionally, the iio_chan_spec for
magn_3d_channels is configured to be IIO_CHAN_INFO_RAW. Therefore, this
patch replaces the magic number 0 for the appropriate IIO_CHAN_INFO_RAW.

- Add missing pinctrl description. Support is made optional as dfsdm
  may use internal sources (e.g. via registers)
- Fix typo in IIO STM32 DFSDM filter "MANCH_F" description.
Basically, this should be "falling edge = logic 0", not "1" that applies
to "MANCH_R".
BTW, make the description complete by describing both rising/falling
edges as described in reference manuals.

If an application set a tight sampling frequency, given the interrupt
use is a wakeup source, suspend will not happen: the kernel will receive
a wake up interrupt and will cancel the suspend process.

Given cros_ec sensors type is non wake up, this patch adds prepare and
complete callbacks to set 1s sampling period just before suspend. This
ensures the sensor hub will not be a source of interrupt during the
suspend process.

The resistance member in ccs811_reading struct is an unsigned 16-bit
integer variable used to store RAW_DATA register bytes read from CCS811.
It is kind of misleading to name this struct member as resistance.

About the RAW_DATA register bytes, the CCS811 datasheet states that:
-----
Two byte read only register which contains the latest readings from the
sense resistor.

The most significant 6 bits of the Byte 0 contain the value of the current
through the sensor (0μA to 63μA).

The lower 10 bits contain (as computed from the ADC) the readings of the
voltage across the sensor with the selected current (1023 = 1.65V)"
-----

Hence, the RAW_DATA register byte contains information about electric
current and voltage of the CCS811 sensor. Calling this struct member
'resistance' is kind of misleading, although both electric current and
voltage are needed to calculate the electrical resistance of the sensor
using Ohm's law, V = I x R, in which a new channel type of IIO_RESISTANCE
may be added to the driver in the future.
