Subject: [PATCH 0/2] 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.
