crypto: dh - constify struct dh's pointer members
struct dh contains several pointer members corresponding to DH parameters: ->key, ->p and ->g. A subsequent commit will introduce "dh" wrapping templates of the form "ffdhe2048(dh)", "ffdhe3072(dh)" and so on in order to provide built-in support for the well-known safe-prime ffdhe group parameters specified in RFC 7919. These templates will need to set the group parameter related members of the (serialized) struct dh instance passed to the inner "dh" kpp_alg instance, i.e. ->p and ->g, to some constant, static storage arrays. Turn the struct dh pointer members' types into "pointer to const" in preparation for this.
