Third set of IIO new device support cleanups and fixes for the 5.5 cycle.

New device support
* ad5446
  - Support the ad5600 DAC (id only needed).
* ad7292 ADC DAC etc
  - New driver plus dt-bindings.
* veml6030 ambient light sensor
  - New driver plus dt-bindings and sysfs docs.

Features
* mpu6050
  - Explicit VDD control.
* stm32-adc
  - Allow limiting of max clock frequency from devicetree to ensure it's
    suitable for external circuitry.

yaml binding conversions
* ltc1660
* mcp3911

Fixes
* adis16480
  - Fix wrong scale factors.
  - Fix debugfs reg access by providing the callback.
* cros_ec_baro
  - Fixing missing mask entry to make available sample frequencies visible
    in sysfs.
* st_lsm6dsx
  - Explicitly handle different ODR table sizes.
  - Handle restrictions between slave ODR and accel ODR when
    both are enabled.
  - Allow ODR to be expressed more accurately by using miliHz.
* tools
  - Fix an issue with parallel builds.

Cleanups and warning fixes
* adis16136, adis16400, adis16460, adis-lib
  - Change some checks on return values to be for 0 rather than strictly
    negative. Avoids some fiddly issues with the compiler concluding some
    variables are initialized due to a mixture of error checks.
  - Assign values only on success of 'read' operations - avoiding any
    chance the compiler will falsly suggest they might be used uninitialized.
  - Whitespace and simlar cleanups.
* aspeed adc
  - devm_platfom_ioremap_resource to reduce boilerplate.
* bcm-iproc-adc
  - Stray semicolon removal.
* cc10001
  - devm_platfom_ioremap_resource to reduce boilerplate.
* dln2-adc
  - Reorganise the buffered mode setup and tear down. Part of moving towards
    being able to refactor this area of the IIO core.
* hdc100x
  - Reorganise the buffered mode setup and tear down.
* ingenic-adc
  - devm_platfom_ioremap_resource to reduce boilerplate.
* lpc18xx-adc
  - devm_platfom_ioremap_resource to reduce boilerplate.
* lpc18xx-dac
  - devm_platfom_ioremap_resource to reduce boilerplate.
* mt6577
  - devm_platfom_ioremap_resource to reduce boilerplate.
* npcm
  - devm_platfom_ioremap_resource to reduce boilerplate.
* rcar-gyroadc
  - devm_platfom_ioremap_resource to reduce boilerplate.
* spear-adc
  - devm_platfom_ioremap_resource to reduce boilerplate.
* vf610-adc
  - devm_platfom_ioremap_resource to reduce boilerplate.
* vf610-dac
  - devm_platfom_ioremap_resource to reduce boilerplate.
