Add support for the ROHM BD79105 ADC
(and do some minor simplifications to the ad7476 driver while at it).

The first 2 patches were originally sent as an RFC:
https://lore.kernel.org/all/cover.1754041258.git.mazziesaccount@gmail.com/

Revision history:
  v2 => v3:
   - Drop 5/10 "Limit the scope of the chip_info"
   - Add 5/10 "use *_cansleep GPIO APIs"
   - Multiple fixes as suggested during v2 review. More accurate
     changelog included in individual patches

  v1 => v2:
   - Two new patches:
     5/10 "Limit the scope of the chip_info" and
     6/10 "Drop convstart chan_spec"
     Please, let me know if you think some of the changes should be
     squashed.
   - Multiple fixes as suggested during v1 review. More accurate
     changelog included in individual patches

  Simplification RFC => ROHM BD79105 support series v1:
   - Use spi_get_device_match_data()
   - Fix uV to mV conversion
   - Rewording of commit message
   - Added patches 3 to 8.

This version LGTM
Reviewed-by: Andy Shevchenko <andy@kernel.org>
with the exception of patches for DT and MAINTAINERS, I haven't even
looked at them.

I took another quick look and just a few comments on the DT patch
which also need a DT maintainer review.
