configfs: Allow the registration of const struct configfs_attribute
The attribute structure defined in driver code never need to be
modified. Allow them to be marked as const.
As there are many drivers which use these attributes, prepare for a
phased transition by using a union of const and non-const attributes.
After all drivers have been migrated to the const variant, the non-const
one can be replaced by the const one and the transition machinery will
be removed again.
