cnss2: Create new infrastructure for removing sysfs group

Up until kernel 6.1, devm_device_remove_group() was used when
removing sysfs group. From kernel 6.2 onwards,
devm_device_remove_group() is no longer supported. Thus, create
new functions that replicate original functionality of
devm_device_remove_group().
