This new function allows us to perform debug checks in the helper to ensure
that the overrun does not occur. Use it in all the simple cases where
either a static buffer or a structure is used in the drivers.

REGCACHE_NONE is the default type of the cache when not provided.
Drop unneeded explicit assignment to it.
Note, it's defined to 0, and if ever be redefined, it will break
literally a lot of the drivers, so it very unlikely to happen.

Use this new type to both slightly simplify the code and avoid
confusing static analysis tools. Mostly this series is about consistency
to avoid this code pattern getting copied into more drivers.

Add mising braces after an if condition that contains scoped_guard().
This style is both preferred and necessary here, to fix warning after
scoped_guard() change in commit fcc22ac5ba ("cleanup: Adjust
scoped_guard() macros to avoid potential warning") to have if-else inside
of the macro. Current (no braces) use in af8133j_set_scale() yields
the following warnings:
af8133j.c:315:12: warning: suggest explicit braces to avoid ambiguous 'else' [-Wdangling-else]
af8133j.c:316:3: warning: add explicit braces to avoid dangling else [-Wdangling-else]

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While add it, also remove commas after the sentinel entries.
