Second set of new device support, cleanups and features for IIO in the 5.8 cycle

Usual mixed back but with a few subsystem wide or device type
wide cleanups.

New device support

* adis16475
  - New driver supporting adis16470, adis16475, adis16477, adis16465,
    adis16467, adis16500, adis16505 and adis16507.
    Includes some rework of the adis library to simplify using it
    for this new driver.
* ak8974
  - Add support for Alps hscdt008a. ID only. Related patches add support
    for scale.
* atlas-sensor
  - Add support for RTD-SM OEM temperature sensor.
* cm32181
  - Add support for CM3218 including support for SMBUS alert via
    ACPI resources.
* ltc2632
  - Add support for ltc2634-12/10/8 DACS including handling per
    device type numbers of channels.

Major Features

* cm32181
  - ACPI bindings including parsing CPM0 and CPM1 custom ACPI tables.
    Includes minor tidy ups and fixes.
* vcnl4000
  - Add event support
  - Add buffered data capture support
  - Add control of sampling frequency

Cleanups and minor fixes.

* core
  - Trivial rework of iio_device_alloc to use an early return and
    improve readability.
  - Precursors to addition of multiple buffer support. So far
    minor refactoring.
* subsystem wide
  - Use get_unaligned_be24 slightly improve readability over open
    coding it.
* adis drivers
  - Use iio_get_debugfs_dentry access function.
* bh1780, cm32181, cm3232, gp2ap02a00f, opt3001, st_uvis25, vl6180,
  dmard06, kxsd9
  - Drop use of of_match_ptr to allow ACPI based probing via PRP0001.
    Part of clear out of this to avoid cut and paste into new drivers.
* ad5592r, ad5593r
  - Fix typos
* ad5933
  - Use managed interfaces to automate error handling and remove.
* ak8974
  - Fix wrong number of 'real bits' for buffered data.
  - Refactor to pull measurement code out as separate function.
    bmp280
  - Fix lack of clamp on range during data capture.
* at91-sama5d2_adc
  - Handle unfinished conversions correctly.
  - Allow use of triggers other than it's own.
  - Reorganize buffer setup and tear down as part of long running
    subsystem wide rework.
* ccs811
  - Add DT binding docs and match table.
  - Support external reset and wakeup pins.
* hid-sensors
  - Reorganize buffer setup and tear down as part of long running
    subsystem wide rework.
* ltr501
  - Constify some structs.
* vcnl4000
  - Fix an endian issue by using explicit byte swapped i2c accessors.
