Subject: [PATCH] hwmon: (gsc-hwmon) constify read-only struct regmap_bus

`gsc_hwmon_regmap_bus` is not modified and can be declared as const to
move its data to a read-only section.

I missed this one when converting regmap_config to const. After this
conversion, all read-only regmap_* structs in hwmon are declared as
const.
