Statically allocated array of pointed to hwmon_channel_info can be made
const for safety.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

This depends on hwmon core patch:
https://lore.kernel.org/all/20230406203103.3011503-2-krzysztof.kozlowski@linaro.org/

Therefore I propose this should also go via hwmon tree.

I am not going to apply patches for 10+ subsystems through the hwmon tree.
This can only result in chaos. The dependent patch is available at

git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging.git hwmon-const

or wait until after the next commit window to apply this patch.

Thanks,
Guenter
