Subject: [PATCH v2 0/7] ROHM BU27034NUC to ROHM BU27034ANUC

As discussed here:
https://lore.kernel.org/all/ff8d6d14-6b48-4347-8525-e05eeb9721ff@gmail.com/

The ROHM BU27034NUC was cancelled before it entered mass-production. A
replacement was developed and named to BU27034ANUC. (Note the added
'A' in the model name). The BU27034ANUC has several changes that make
the old BU27034NUC driver unusable with it. I was told the old BU27034NUC
should not be encountered anywhere.

Hence, this series converts the rohm-bu27034.c to support the new
BU27034ANUC instead of the obsoleted BU27034NUC. Additionally, the
series adds a read-only entry for the HARDWAREGAIN to help understanding
what part of the scale is contributed by the gain, and what by the
integration time. This is useful when figuring out why some transitions
from one 'scale' to other are failing.

Revision history:
	v1 => v2:
		- Split the one large patch to patches 3 - 6 for easier
		  review. (Please let me know if you wish me to squash
		  them to one).
		- Introduce new compatible for the BU27034ANUC and drop
		  the old one.
		- Add styling fixes as suggested by Jonathan
		- Fix the lux calculation coefficient selection logic
