This series suggests some simplifications to the ad7476 ADC. It is
currently 100% untested, and shouldn't be merged as is. I'd like to hear
opinions on these changes before adding support to the ROHM BD79105 ADC.

Intention of the patch 1 is pretty trivial. I'd just like to hear if
people think the enum + ID table approach is preferred over direct
pointers to IC specific structs in SPI device's driver_data.

Real reason for the RFC version is the patch 2. It aims to clear the
supply handling logic. I did also an alternate version which requires
the names of the regulators to be provided in the chip_data:
https://github.com/M-Vaittinen/linux/commit/cf5b3078feb17f9a0069b2c7c86f6d980e879356

I believe the version in the link --^
is clearer, but it can potentially help people to add issues with supply
enable ordering.

I can't still say if the patch 2 contained in this series is better, or
if the one behind the link is better way to go. So, RFC it is :)
