First set of new device support, features and cleanups for IIO in the 5.11 cycle

Usual mixed bag of new drivers / device support + cleanups etc with the
addition of a fairly big set of yaml conversions.

Txt to yaml format conversions.
In some cases dropped separate binding and moved to trivial devices (drop).

* Drop iio_buffer_set_attrs()
* Centralize ioctl call handling. Later fix to ensure -EINVAL returned if
  no handler has run.
* Fix an issue with IIO_VAL_FRACTIONAL and negative values - doesn't affect
  any known existing drivers, but will impact a future one.
* kernel-doc fix in trigger.h
* file-ops ordering cleanup

Features

  - Adapt clock duty cycle for proper functioning. Note no known problems
    with existing boards.
* st,vl53l0x-i2c
  - Put back i2c_device_id table as needed for greybus probing.
* vishay,vcnl4035
  - Put back i2c_device_id table as needed for greybus probing.

-
-Optional properties:
-

-	* DIO1
-	* DIO2
-	* DIO3
-	* DIO4
-	If this field is left empty, DIO1 is assigned as default data ready
-	signal.
-- reset-gpios: must be the device tree identifier of the RESET pin. As the line
-	is active low, it should be marked GPIO_ACTIVE_LOW.
-- clocks: phandle to the external clock. Should be set according to
-	"clock-names".
-	If this field is left empty together with the "clock-names" field, then
-	the internal clock is used.
-- clock-names: The name of the external clock to be used. Valid values are:
-	* sync: In sync mode, the internal clock is disabled and the frequency
-		of the external clock signal establishes therate of data
-		collection and processing. See Fig 14 and 15 in the datasheet.
-		The clock-frequency must be:
-		* 3000 to 4500 Hz for adis1649x devices.
-		* 700 to 2400 Hz for adis1648x devices.
-	* pps: In Pulse Per Second (PPS) Mode, the rate of data collection and
-	       production is equal to the product of the external clock
-	       frequency and the scale factor in the SYNC_SCALE register, see
-	       Table 154 in the datasheet.
-	       The clock-frequency must be:
-	       * 1 to 128 Hz for adis1649x devices.

-	Valid values are:
-	* DIO1
-	* DIO2
-	* DIO3
-	* DIO4
-	Each DIOx pin supports only one function at a time (data ready line
-	selection or external clock input). When a single pin has two
-	two assignments, the enable bit for the lower priority function
-	automatically resets to zero (disabling the lower priority function).
-	Data ready has highest priority.
-	If this field is left empty, DIO2 is assigned as default external clock

-  (This binding is taken from pinctrl/pinctrl-bindings.txt)
-  If the requested interrupt is configured as IRQ_TYPE_LEVEL_HIGH or

-  when it is not active, whereas a pull-up one is needed when interrupt
-  line is configured as IRQ_TYPE_LEVEL_LOW or IRQ_TYPE_EDGE_FALLING.
-- interrupts: interrupt mapping for IRQ. It should be configured with

-  IRQ_TYPE_EDGE_FALLING.
-- wakeup-source: Enables wake up of host system on event.
